• Biopsy for asymptomatic postmenopausal women if endometrial thickness is ≥8 mm. • For 4-8 mm, consider biopsy after evaluating risk factors and blood flow signals. To determine the cutoff value for endometrial thickness (ET) that prompts a biopsy in asymptomatic postmenopausal women with an incidental finding of thickened endometrium, and to develop a risk prediction model. This is a retrospective cohort analysis of the clinical records of the Hysteroscopic Center of Fu Xing Hospital, Capital Medical University, Beijing, China. We collected asymptomatic postmenopausal women who presented with an ET of ≥4 mm (double-layer) as an incidental finding. We stratified the participants into non-malignant and malignant groups based on pathology results and assessed differences between the two groups. A receiver operating characteristic curve (ROC) was used to identify the cutoff value of ET for predicting endometrial malignancy. Logistic regression models were also constructed to predict the risk of malignancy. A total of 581 consecutive eligible cases were included. The optimal cutoff value for ET was 8 mm, with a maximum area under the curve (AUC) of 0.755 (95 % CI: 0.645–0.865). In addition to ET, the regression model incorporated diabetes, blood flow signal, BMI, and hypertension to predict the risk of malignancy. A ROC curve constructed for the model yielded an AUC of 0.834 (95 % CI: 0.744–0.924). It is reasonable to offer hysteroscopy and visually-directed endometrial biopsy for asymptomatic postmenopausal women when ET is 8 mm or above. For those with an ET between 4 and 8 mm, further decision to perform biopsy should be determined on an individual basis, considering risk factors and blood flow signals of the endometrium.

Simple Summary: Pituitary neuroendocrine tumors (PitNETs) comprise a large panel of histological types and usually require a multidisciplinary team for diagnosis and management. The most common are clinically and biochemically non-functioning PitNETs, and among them are incidentally found masses of pituitary incidentalomas (PIs), which have an increasing rate of detection currently. PIs are diagnosed in 10% of the population (up to 40% in some studies), and they may be confirmed at any age, mostly by computed tomography (CT) or magnetic resonance imaging (MRI). The rate of PIs growth varies from 5% to 50% depending on the tumor size, but micro-adenomas generally have a lower rate of enlargement. Long-term follow-up is advised, yet standard protocols are not homogenous. Overall, forestalling the tumor's spontaneous evolution is still an open issue. Non-functioning (NF) accidentally detected PitNETs (PIs) are common findings of CT/MRI scans currently. Data concerning their behavior vary, and some PIs will potentially experience a size change over time that might become clinically relevant. Objective: We aimed to evaluate CT-related PIs diameters following 3 aspects: a cross-sectional analysis based on the age' groups at first PI diagnosis and on the gender distribution and a longitudinal analysis in PIs with <0.5 cm versus ≥0.5 cm as the largest diameter at baseline. Methods: A retrospective, real-life, multi-centric study in adults with NF micro-PIs was performed. Results: 208 subjects (92.79% females) were included (average age 43.18 ± 12.58 y). The mean largest diameter (between transversal and longitudinal diameters) was 0.55 ± 0.16cm, and 44.71% of the PIs were located on the right part of the pituitary gland. The patients were divided into 10 age-groups (21 to 70 y), and no difference was observed between the mean largest diameters of these groups (p = 0.693). Females and males had a similar age at PIs diagnosis (p = 0.353), transverse diameter (p = 0.910), longitudinal diameter (p = 0.229), and PI location (p = 0.368). Serial CT scans (2 to 4 per patient) included a median (Q1–Q3) of 20 (12–36) months for the second CT scan, 58 (36–84) for the third CT scan, 78 (53–118) for the fourth CT scan, and a total follow-up between baseline and last CT scan of 40 (13–72) months. The initial largest diameter correlated with the diameter change between the baseline and the last CT (r = −0.575, p = 0.000). The largest PI diameter was similar between each serial CT scan (p = 0.840). According to the cut-off value of 0.5 cm diameter (for initial largest tumor diameter), group A (N = 78, 37.50%, <0.5 cm) and group B (N = 130, 62. 50%; ≥0.5 cm) had similar age at baseline (43.83 ± 12.72 versus 42.79 ± 12.54 y, p = 0.565) and PIs locations (right, left, median). The largest PI diameter remained smaller in group A versus B amid the second CT scan (p = 0.000) and the last CT scan (p = 0.009). The largest diameter change from the first to the last CT scan showed an increase in group A (median of +0.10 cm, p = 0.000) and a decrease in group B (median of −0.01 cm, p = 0.002); this diameter change was different in group A versus B (p = 0.000). The cumulative probability of tumor-growth-free survival showed different survival functions (log rank p = 0.000): group A exhibited a more gradual decrease versus B; at 60 months, the cumulative probability was 0.32 ± 0.08 for group A versus 0.75 ± 0.07 for B. During follow-up, all PIs remained NF, and no hypopituitarism was noted (as limits, we mention that dynamic hypopituitarism testing was selectively performed). Conclusions: NF micro-PIs in adults showed a similar age and sex distribution. During follow-up, PIs with a largest diameter < 0.5 cm increased after a median of 40 months but remained <1 cm, while in PIs with ≥0.5 cm, the largest diameter decreased. This highlights a lower predictability in tumor behavior than expected, particularly in larger micro-PIs that, overall, remained without relevant clinical implications after surveillance.

CT and MRI scans of the shoulder can lead to the identification of incidental findings (IF), which can have a major impact on the further treatment of the patient. The aim of this retrospective study was to record the prevalence of IF, incidentalomas (IT) and malignant IT for CT and MRI examinations of the shoulder and to investigate the effect of patient characteristics on the statistical occurrence of IF, IT and malignant IT. A total of 903 shoulder examinations (415 CT, 488 MRI) were retrospectively analyzed for the presence of IF, subsequently categorized (harmless IF, IT requiring clarification, malignant IT) and analyzed regarding patient characteristics. The statistical analysis was carried out using independent t- and chi-square tests. A significance level of p < 0.05 was set. Among the 903 patients evaluated (436 female, 467 male), 153 (16.9%) patients experienced IF (harmless IF: 101 (11.2%) patients, IT: 94 (10.4%), malignant IT: 4 (0.4%). The average age of the patients without IF and IT was significantly lower compared to the patients with IF and IT (p < 0.001). While IF occurred in 31.1% of the CT, IF was only detected in 4.9% of the MRI (p < 0.001). IF have a high prevalence (16.9%), especially in CT examinations of the shoulder, which increases with age. The exact detection and initiation of appropriate therapy is of great clinical importance, as early detection of life-threatening diseases enables more effective treatment and a potential gain in health and lifespan.

Incidental findings are unrelated to a patient's complaint, found on diagnostic imaging, such as point-of-care ultrasound (POCUS). Incidental findings represent potential harms to patients and may lead to increased patient anxiety and health care costs related to downstream testing and surveillance. In this study, we aimed to calculate the rate of incidental renal cysts found by POCUS. Further, we hoped to describe how emergency physicians relay the findings to patients. Lastly, we hoped to examine if patients suffered harms in the 12 months following identification of an incidental renal cyst. From our single-center, academic emergency department (ED), we reviewed renal POCUS images from 1000 consecutive adult ED patients to determine if there was a renal cyst. Next, we performed manual chart review to determine if patients were informed of the incidental renal cyst or suffered any patient harms. We found the prevalence of renal cysts to be 6.5% (95% confidence interval: 4.9%–8.4%). Those with cysts were more likely to be older compared to those without (63 ± 14 vs. 49 ± 15 years of age). Only 8% of patients had evidence that they were informed of their incidental renal cyst. No patients received a biopsy or were diagnosed with renal cell carcinoma or polycystic kidney disease. Incidental renal cysts are common and are more likely to be found in older adults. In our study, physicians infrequently informed patients of their incidental finding. [ABSTRACT FROM AUTHOR]

Screening of the general population for cancer is a matter of primary prevention reducing the burden of disease. Whilst this is successful for several cancers including breast, colon and prostate, the situation to screen and hence prevent pancreatic cancer is different. The organ is not as accessible to simple physical exam or biological samples (fecal or blood test). Neither exists a blood test such as PSA that is cost-effective. Reviewing the evidence from screening risk groups for pancreatic cancer, one must conclude that there is no rational at present to screen the general population, for a lack of appropriate tests.

Background: Sickle cell disease (SCD) is a genetic hematological disorder associated with severe complications, such as vaso-occlusive crises, acute chest syndrome (ACS), and an increased risk of thromboembolic events, including pulmonary embolism (PE). The diagnosis of PE in SCD patients presents challenges due to the overlapping symptoms with other pulmonary conditions. Our previous study revealed that nearly 96% of computed tomography pulmonary angiography (CTPA) scans in SCD patients were negative for PE, highlighting a gap in understanding the significance of CTPA findings when PE is absent. Methods: In this retrospective follow-up study conducted at the Salmaniya Medical Complex in Bahrain, we examined SCD patients with HbSS genotypes who underwent CTPA from January 1, 2018, to December 31, 2021, for suspected PE, but the results were negative. The aim of this study was to identify alternative diagnoses and incidental findings from CTPA scans. Experienced radiologists reviewed the CTPA images and reports to assess potential alternative diagnoses and incidental findings, incorporating an additional analysis of chest X-rays to evaluate the diagnostic value of CTPA. Incidental findings were classified based on their location and clinical significance. Results: Among the 230 evaluated SCD patients (average age 39.7 years; 53% male) who were CTPA negative for PE, 142 (61.7%) had identifiable alternative diagnoses, primarily pneumonia (49.1%). Notably, 88.0% of these alternative diagnoses had been previously suggested by chest radiographs. Furthermore, incidental findings were noted in 164 (71.3%) patients, with 11.0% deemed clinically significant, necessitating immediate action, and 87.8% considered potentially significant, requiring further assessment. Notable incidental findings included thoracic abnormalities such as cardiomegaly (12.2%) and an enlarged pulmonary artery (11.3%), as well as upper abdominal pathologies such as hepatomegaly (19.6%), splenomegaly (20.9%), and gallstones (10.4%). Conclusion: This study underscores the limited additional diagnostic yield of CTPA for identifying alternative diagnoses to PE in SCD patients, with the majority of diagnoses, such as pneumonia, already suggested by chest radiographs. The frequent incidental findings, most of which necessitate further evaluation, highlight the need for a cautious and tailored approach to using CTPA in the SCD population. [ABSTRACT FROM AUTHOR]

IntroductionRoot resorption is a destructive process that compromises tooth structure and can result in tooth loss. Often it remains asymptomatic and is an incidental finding on radiographic examinations. The purpose of this study was to determine prevalence and characteristics of root resorption in patients referred for cone-beam computed tomography (CBCT) imaging for a variety of indications.MethodsThe study included CBCT scans of 1086 consecutive patients referred for CBCT imaging over an 18-month period. A total of 1148 scans were acquired. Data were abstracted from radiology reports, and prevalence estimates of resorption were computed for the aggregate sample and also across specific indications.ResultsResorption was identified in 171 patients (15.7%, 95% CI: 13.6%-17.9%) and in 249 teeth with a prevalence range of 2.6%-92.3% across specific indications. An 18.7% of the patients had 2 resorption sites whereas 8.8% had 3 or more resorption sites. The majority of affected teeth were anteriors (43.8%), followed by molars (40.6%) and premolars (14.5%). The most prevalent resorption types were external (29.3%), cervical (22.5%), infection-induced apical resorption (13.7%), internal (9.6%), and impacted tooth induced (8.8%). The majority of teeth with resorption did not have prior endodontic treatment (73.9%) and had radiographically normal periapex (69.5%). Of 249 teeth with resorption, 31% presented as incidental finding. The prevalence of incidental findings of resorption increased with age, P

The mandibular foramen and its canal are one of the most important structures in the skull, as they solely supply the mandible through their associated nerves and vessels. Many anatomical variations have been reported in the literature until now, and this case report represents a clear-cut appearance of its shape in a panoramic radiograph, which is not mostly seen in normal panoramic radiographs. These factors are of utmost importance when it comes to performing various surgeries and preventing complications due to their varied anatomy, which will allow dentists to create a better treatment plan and provide better treatments without any complications.

Introduction: Undifferentiated sarcoma is considered a rare and aggressive type of soft tissue sarcoma with the lower extremity reported as the common site for soft tissue sarcomas. Case presentation: We present a rare incidental finding of undifferentiated sarcoma during lower limb Doppler ultrasound with a presenting symptom of right thrombotic-like calf pain in a 49-year-old female. Discussion: On ultrasound, the presented undifferentiated sarcoma appeared as a large heterogeneous, oval-shaped, soft tissue mass deeply seated in the right calf with involvement of the soleus muscle. The features on ultrasound mimicked those of a hematoma; however, the possibility of the lesion being a haematoma was promptly ruled out with the demonstration of internal vascularity on colour Doppler application. The case was then referred to a sarcoma triage multidisciplinary team for a review. Magnetic resonance imaging, computed tomography and biopsy were parts of the diagnostic workup for this case, histology confirmed the soft tissue lesion to be an undifferentiated sarcoma. Emergency above knee amputation of the right leg was performed as part of the patient's treatment. Conclusion: This case report presents a rare incidental finding of undifferentiated sarcoma encountered during lower limb Doppler ultrasound causing thrombotic-like calf pain. Sonographers are encouraged to pay necessary attention and carefully examine any adjacent and incidental soft tissue lesion during lower limb Doppler ultrasound using compression, two-dimensional imaging and colour imaging, especially those that appear with characteristic features of malignancy; urgent referral should be made of such cases to a tertiary soft tissue sarcoma centre for further evaluation and management.

A radiographic examination is a follow-up procedure that can reveal diagnostic information that is difficult to acquire through a clinical examination alone. The objective of this study was to determine the frequency distribution of the incidental findings from panoramic images of partially edentulous patients. This cross-sectional study used 385 panoramic images of partially edentulous patients. The images were evaluated for all incidental findings. The independent variables were dental status divided into dentulous and partially edentulous, patient age divided into three groups comprised of Group 1 (17–40 years), Group 2 (41–64 years), and Group 3 (65–87 years), sex (female or male), and the location of the incidental finding (maxillary or mandibular). The dependent variables were the type of incidental finding, which included impacted teeth, residual tooth roots, foreign bodies, radiolucent/mixed/radiopaque lesions, maxillary atrophy, and an abnormal mandibular cortical width (MCW). In order of frequency, the three most common incidental findings were a mandibular lower border width of <3.0 mm, radiolucent/mixed/radiopaque lesions, and maxillary atrophy. The highest proportion of incidental findings of impacted teeth was in Group 1. As for root remains, foreign bodies, radiolucent/mixed/radiopaque lesions, maxillary atrophy, and a mandibular lower border cortical width of <3.0 mm, these findings were most commonly seen in Group 3. The prevalence of having at least one incidental finding on a panoramic radiograph of a partially edentulous patient was relatively high at 71.95% (277 radiographs). [ABSTRACT FROM AUTHOR]

Objectives: To investigate the prevalence of incidental findings and need for further dental treatment and analyse the influence of size of field-of-view (FOV) and age in cone beam computed tomography (CBCT) for pre-implant planning. Methods: 404 CBCT scans were examined retrospectively for incidental findings and need for further dental treatment. Incidental finding-frequencies and need for further treatment were assessed for different age (< 40 years, 40–60 years, > 60 years) and FOV groups (small, medium, large). Intraexaminer and interexaminer agreements were evaluated. Results: In 82% of the scans at least one incidental finding was found, with a total of 766 overall. More incidental findings were found in scans with large FOV (98% vs. 72%, OR = 22.39 large vs. small FOV, p < 0.0001) and in scans of patients > 60 years (OR = 5.37 patient's age > 60 years vs. < 40 years, p = 0.0003). Further dental treatment due to incidental findings was needed in 31%. Scans with large FOV were more likely to entail further treatment (OR = 3.55 large vs. small FOV, p < 0.0001). Partial edentulism and large FOV were identified as risk factors for further treatment (p = 0.0003 and p < 0.0001). Further referral of the patient based on incidental findings was judged as indicated in 5%. Intra- and inter-examiner agreements were excellent (kappa = 0.944/0.805). Conclusions: A considerable number of incidental findings with need for further dental treatment was found in partially edentulous patients and in patients > 60 years. In pre-implant planning of elderly patients, the selection of large FOV CBCT scans, including dentoalveolar regions not X-rayed recently, help to detect therapeutically relevant incidental findings.

Objective: Incidental findings (IFs) are newly discovered abnormal findings unrelated to the primary purpose of imaging. Brain computed tomography (CT) scan is one of the most essential and initial imaging evaluations for head trauma patients, which may also have nontraumatic IFs. We aim to investigate the prevalence and nature of IFs in brain CT scans of head trauma patients. Methods: We conducted a cross-sectional study to evaluate brain CT scans of 1006 head trauma patients over one year (April 2021 to March 2022), to identify incidental findings by consensus agreement of two radiologists. We categorized the incidental findings into four categories based on appropriate follow-up recommendations. Results: We included 1006 head trauma patients who underwent brain CT scan, of which 126 incidental findings were discovered in brain CT scan of 107 patients. The prevalence of incidental findings was 10.6% (107/1006). The most common incidental finding was brain atrophy (n=15, 11.9%). The mean age of patients with IFs was significantly higher than those without IFs, but there was no difference between the two groups regarding gender. Conclusion: The discovery rate of incidental findings of brain CT scans in head trauma patients was considerable. Serious medical findings that need immediate evaluation were found in 5.6% of patients, mostly over the age of 40. Therefore, patients who have clinically significant incidental findings need improved documentation and follow-up to evaluate the long-term outcomes and reliability of imaging results.

Introduction: The aim of the study was to investigate prevalence and impact of incidental renal masses (IRMs) accompanying increasing computed tomography (CT) work-up for symptomatic aortic valve stenosis (sAVS) of the elderly with regard to the relevance of urological consultation for overall survival (OS). Methods: A retrospective analysis of pre-transcatheter aortic-valve implantations (TAVIs) CT scans of patients with sAVS (N = 1,253) harboring IRM was performed for 2014–2019. According to the clinical management, groups 1 (urologic consultation) and 2 (findings ignored) were formed and analyzed in terms of OS. Results: The prevalence of IRM was 9% (119/1,253). In 19% (23/119), urological advice was sought (group 1). At baseline, group 1 showed a significantly higher rate of malignancy-specific lesions compared to 2 (p < 0.01). Other clinical parameters (e.g., age, cardiological scores, comorbidities) did not differ between groups (p > 0.05). In group 1, 4 (17%) findings were histologically confirmed, of which 3 (13%) underwent surgery. There was no significant difference in median OS at a median follow-up of 24.7 months between groups 1 and 2 with 35.7 (95% CI, 5.9; 65.4) and 47.4 months (95% CI, 33.0; 61.7), respectively (p = 0.4). In Cox regression analysis, chronic kidney disease but not urologic work-up or chronic obstructive pulmonary disease or heart failure emerged as an independent unfavorable predictor of OS (HR 2.44, 95% CI 1.37; 4.36, p = 0.003). Conclusion: For the first time, a TAVI population with IRM was analyzed from the urologist's perspective. Urologic co-evaluation and work-up does not confer a significant benefit in terms of OS in this particular population. [ABSTRACT FROM AUTHOR]

Introduction: Intracranial arachnoid cysts (IAC) in children are a common incidental finding on imaging. Most IACs are asymptomatic and can be monitored; however, a small percentage may enlarge and require surgical intervention. This study aimed to identify clinical risk factors in patients with IAC who underwent surgery versus those who did not. Methods: We conducted a retrospective chart review from 2009 to 2021 at a free-standing children's hospital. A total of 230 patients diagnosed with an IAC aged 0–21 years of age were included in the study. Data on demographics, imaging, and neurological follow-up were analyzed. Results: Out of 230 patients, 45 (19.6%) underwent surgery. At time of IAC diagnosis, the surgical patients were younger (median age 1.1 years), and their median cyst volume was larger (41.7 cm3), compared to nonsurgical patients (median age 5.9 years, volume 11.8 cm3, respectively). Headache was the most common reason for initial imaging in nonsurgical patients (54/185, 29.2%) while prenatal ultrasound (11/45, 24.4%) and macrocephaly (11/45, 24.4%) were the most common reasons for surgical patients. The majority of both surgical and nonsurgical patients had the IAC incidentally found (41/45, 91.1% and 181/185, 97.8%, respectively). Surgery relieved symptoms in 38/45 (84.4%) patients. Cyst volume and age were predictors of increased odds of having surgery. Discussion/Conclusion: Patients who underwent surgery were younger and had larger cyst volumes at time of diagnosis. The majority of the IAC were found incidentally and remained stable over prolonged follow-up. The majority of the patients experienced relief of symptoms postsurgical intervention. There is a greater odds of having surgical treatment with decreased age and greater cyst volume at diagnosis, and therefore these patients should be monitored closely for development of symptoms indicating need for surgical intervention. Plain Language Summary: Pediatric imaging findings of brain cysts are a common finding. Some cysts do not require surgical intervention while others may require surgery. We conducted a retrospective chart review from 2009 to 2021 on patients aged 0–21 years of age who were found to have a brain cyst on imaging reports. Our aim was to identify clinical risk factors in patients with brain cysts who underwent surgery versus those who did not. A total of 230 patients were included in the study, of which 45 (19.6%) underwent surgery. Overall, surgical patients were younger (median age 1.1 years) and had a median cyst volume larger (41.7 cm3), compared to nonsurgical patients (median age 5.9 years, volume 11.8 cm3, respectively). The most common reason to undergo initial imaging was headache for nonsurgical patients (54/185, 29.2%) while surgical patients had initial imaging due to large head size (11/45, 24.4%) or imaging carried out prenatally to 1 year of life (11/45, 24.4%). We found that cyst volume and age at diagnosis were predictors for surgical intervention. The greater the cyst volume was at initial diagnosis and the younger the patient was at time of diagnosis, the greater the odds the patient had of undergoing surgical intervention. Therefore these patients should be monitored closely for development of symptoms indicating a need for surgical intervention. [ABSTRACT FROM AUTHOR]

Background The incidental finding of a pericardial effusion (PE) poses a challenge in clinical care. PE is associated with malignant conditions or severe cardiac disease but may also be observed in healthy individuals. This study explored the prevalence, determinants, course, and prognostic relevance of PE in a population‐based cohort. Methods and Results The STAAB (Characteristics and Course of Heart Failure Stages A/B and Determinants of Progression) cohort study recruited a representative sample of the population of Würzburg, aged 30 to 79 years. Participants underwent quality‐controlled transthoracic echocardiography including the dedicated evaluation of the pericardial space. Of 4965 individuals included at baseline (mean age, 55±12 years; 52% women), 134 (2.7%) exhibited an incidentally diagnosed PE (median diameter, 2.7 mm; quartiles, 2.0–4.1 mm). In multivariable logistic regression, lower body mass index and higher NT‐proBNP (N‐terminal pro‐B‐type natriuretic peptide) levels were associated with PE at baseline, whereas inflammation, malignancy, and rheumatoid disease were not. Among the 3901 participants attending the follow‐up examination after a median time of 34 (30–41) months, PE was found in 60 individuals (1.5%; n=18 new PE, n=42 persistent PE). Within the follow‐up period, 37 participants died and 93 participants reported a newly diagnosed malignancy. The presence of PE did not predict all‐cause death or the development of new malignancy. Conclusions Incidental PE was detected in about 3% of individuals, with the vast majority measuring

A 45-year-old male patient with clinically suspected schizophrenia was referred for an MRI brain to look for organicity. An incidental lesion was noted on the right side of the tubercinerium with suspicious findings of osteolipoma. T1 and T2 weighted sequences showed a hyper-intense lesion suggestive of fatty intensity or hemorrhage. A homogenous blooming artefact was seen on gradient imaging suggestive of a calcific/hemorrhagic element. The referring clinician was conveyed the findings asking about the need for further imaging by CT. The patient was started on antipsychotics for schizophrenia. One week later, a CT head was obtained, which showed a fatty density lesion with a smooth, peripheral rim of hyperdensity. The HU value matched rim calcification suggesting radiological diagnosis of osteolipoma. The patient was kept under close observation and no specific therapy was guided to this lesion. The patient was responding well to pharmacotherapy (in terms of control of symptoms) confirming osteolipoma as an incidental finding. This case report establishes the role of adequate imaging in subtle brain lesions which may mimic primary lesion-producing neurological symptoms. The importance of clinical judgment and follow-up in guiding suitable therapy is also highlighted.

Introduction: Aberrant right subclavian artery (ARSA) is the most common of the aortic arch anomalies, occurring in.5% to 1% of the population. There is no standardized follow up protocol, especially in the asymptomatic cases. The purpose of the present study was to evaluate the natural history of ARSA and the role of serial CT scans. Methods: This is a single-center retrospective study of patients with ARSA depicted on chest computed tomography (CT) scans between February 2013 and July 2022. Data were collected from their medical records. Measurements of the aorta at different segments including the aortic diameter at the orifice of ARSA, and ARSA at ostium followed by 1 cm intervals were collected, as well as for follow-up CT scans. Results: 65 patients were diagnosed with ARSA, 70.8% of whom were women. The average age for the cohort was 58.569 ± 16.99 years. The median follow up time was 4 years (range 0-10 years), KM estimated survival after ARSA diagnosis at 1 and 5 years as 97% and 93%, respectively. Nineteen patients had a second CT scan and were included in the morphological CT dynamic analysis, on average of 29 ± 27 months apart (range 7-108). The mean ARSA diameter at origin was larger in the second scan 16.91 ± 4.31 mm compared to the initial scan 16.31 ± 4.96 mm, (P =.04).The mean aortic arch diameter in the first and second CT were 28.54 ± 4.24 and 29.64 ± 5.14 (P =.10), respectively. All other measurements did not disclose any significant enlargement over time. Conclusions: Our cohort demonstrate a benign natural history of ARSA with slow growth rates. However, due to our small sample size we can't draw a clinically sound recommendation on the need for imaging follow up, and further larger cohort with longer follow up interval are required.

Objective The introduction of Targeted Lung Health Checks (TLHC) to screen for lung cancer has highlighted that incidental findings are common and require management strategies. This study analyses retrospectively, incidentally detected breast lesions reported as part of the TLHC referred to the Breast Cancer clinicians. Methods All participants with incidental breast nodules referred to the Breast Cancer team in the first year of screening were reviewed. Results Fifty-two participants (48 female; 92.3%) were referred to the Breast Multidisciplinary Team Meeting for assessment of 43 breast nodules, 8 breast asymmetry/dense breasts, and 2 likely breast related metastatic disease. One participant declined breast team referral. For the 42 breast nodules investigated, the final diagnoses were 5 breast carcinomas, 10 normal breast tissue, and 27 benign nodules. One male patient was diagnosed with breast carcinoma. The 29 breast nodules classified as smooth and well defined were all benign. No malignancy was demonstrated in the group with asymmetric or dense breast tissue. Metastatic breast carcinoma was confirmed in two participants. Twenty-six out of thirty-seven (54%) females had prior breast screening mammograms precluding further investigation. Conclusion Incidental breast nodules are common on THLC scans. Smooth, sharply defined breast nodules are likely to be benign but low-dose CT is poor at accurately assessing breast nodules. Agreed breast referral pathways prior to starting the Lung Cancer Screening programme are recommended. Access to screening mammograms can reduce referrals to the Breast clinic. Advances in knowledge Lessons learned from TLHC pilot studies can be useful to sites commencing national TLHC programme. [ABSTRACT FROM AUTHOR]

It is now well-established that non-invasive prenatal testing (NIPT), originally designed to screen cell-free DNA (cfDNA) in maternal blood for the presence of common fetal trisomies, can lead to incidental detection of occult maternal malignancies. Retrospective evaluations have demonstrated that the detection of multiple copy number alterations in cfDNA is particularly suggestive of an incipient tumor and that cancer detection rates not only depend on tumor biology but also on applied NIPT technologies and downstream diagnostic investigations. Since the identification of a maternal cancer in pregnancy has implications for both woman and the unborn child, prospective studies are needed to provide evidence on best clinical practices and on clinical utility in terms of patient outcomes.

Aortic coarctation is a congenital malformation that is relatively prevalent, occurring in approximately 5 out of every 1000 births. The narrowing typically happens at the aortic isthmus between the left subclavian artery and the arterial ligament. It is frequently associated with a bicuspid aortic valve.Generally, coarctation of the aorta is identified and treated during childhood or early adulthood. If left untreated, this condition can lead to a reduced life expectancy in individuals who have not received treatment.We present a case of a 52-year-old man who complained of chest pain, sputum, and hemoptysis persisting for approximately 2 years. Contrast-enhanced computed tomography (CT) scans revealed the presence of an anterior mediastinal mass, which was later confirmed to be a thymic carcinoma (on histological study). Additionally, an incidental finding of a thoracic aortic coarctation with a well-developed collateral circulation was observed.The discovery of aortic coarctation in adult patients as an incidental finding is rare and particularly uncommon in association with mediastinal or thoracic tumor pathology.Adult and elderly patients with uncorrected coarctation generally have a low survival rate, and the management strategies for such cases are controversial, especially when it is associated to other pathologies.Due to the complexity of therapeutic management and the limited literature available on postsurgical outcomes in these cases, making therapeutic decisions requires a multidisciplinary approach and personalized consideration for each individual case. This approach is necessary to evaluate the risk-benefit ratio and determine the most suitable therapeutic solution.

Riedel's lobe of the liver is a rare anatomical variant often incidentally found on imaging or through the presence of hepatomegaly on physical examination. While patients are usually asymptomatic, the presentation of this condition can vary, ranging from nonspecific symptoms to more severe issues such as torsion, obstruction, rupture, and bleeding. We present a case of a patient with asymptomatic hepatomegaly who was incidentally found to have Riedel's lobe of the liver, accompanied by an elevated IgG mitochondrial antibody. The range of symptoms associated with this rare anatomical variation underscores its importance in diagnosis and surveillance within this patient population. [ABSTRACT FROM AUTHOR]

Abstract Background The incidental finding of thyroid inclusions in lymph nodes of neck dissections of non-thyroid cancer patients is an unusual event. It is still controversial for pathologists about whether this represents benign inclusions or metastatic papillary thyroid carcinoma (PTC). This study is to analyze clinicopathological features of such cases in an attempt to explore their clinical implications. Methods Pathological data were searched for incidentally detected PTC of cervical lymph nodes in non-thyroid cancer cases. Clinicopathological characteristics were reevaluated and recorded. BRAF V600E protein expression and sequencing analysis was then performed in cases with sufficient tissues. Results 31 patients had an incidental finding of PTC in lymph nodes of patients with non-thyroid cancer. BRAF immunohistochemical staining were performed in 17 metastatic lymph nodes with sufficient tumor tissues, and 6 were positive. BRAF V600E point mutation was detected in 5 of 6 BRAF V600E positive cases. Subsequent imaging examinations of the thyroid showed no nodules or calcifications/benign nodules in 20 patients, and suspected malignant nodules in 5 patients. 12 patients underwent total thyroidectomy or ipsilateral lobectomy, and 6 showed PTC in postoperative pathological examinations. The remaining 19 patients without surgery were kept under active surveillance, and no one had recurrence of PTC. Conclusion Incidentally discovered PTC in lymph nodes has usually interpreted as metastasis from a clinical occult thyroid primary cancer, but primary PTC was not always detected. This suggests it could be double occult lesions. With regards to concurrence with highly malignant tumor, most patients could keep regular surveillance.

Fast-paced trauma imaging can result in misses relating to the nonosseous structures included in the field of view. We report a case of a Bosniak type III renal cyst, later found to be clear cell renal cell carcinoma, incidentally noted on post-traumatic CT of the thoracic and lumbar spine. This case includes a discussion of the circumstances which could result in a radiologist missing this finding, the idea of satisfaction of search, the importance of maintaining a thorough search pattern, and the management and communication of incidental findings.

Background Embolic stroke of unknown source (ESUS) accounts for 1 in 6 ischemic strokes. Current guidelines do not recommend routine cardiac magnetic resonance (CMR) imaging in ESUS, and beyond the identification of cardioembolic sources, there are no data assessing new clinical findings from CMR in ESUS. This study aimed to assess the prevalence of new cardiac and noncardiac findings and to determine their impact on clinical care in patients with ESUS. Methods and Results In this prospective, multicenter, observational study, CMR imaging was performed within 3 months of ESUS. All scans were reported according to standard clinical practice. A new clinical finding was defined as one not previously identified through prior clinical evaluation. A clinically significant finding was defined as one resulting in further investigation, follow‐up, or treatment. A change in patient care was defined as initiation of medical, interventional, surgical, or palliative care. From 102 patients recruited, 96 underwent CMR imaging. One or more new clinical findings were observed in 59 patients (61%). New findings were clinically significant in 48 (81%) of these patients. Of 40 patients with a new clinically significant cardiac finding, 21 (53%) experienced a change in care (medical therapy, n=15; interventional/surgical procedure, n=6). In 12 patients with a new clinically significant extracardiac finding, 6 (50%) experienced a change in care (medical therapy, n=4; palliative care, n=2). Conclusions CMR imaging identifies new clinically significant cardiac and noncardiac findings in half of patients with recent ESUS. Advanced cardiovascular screening should be considered in patients with ESUS. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT04555538.

This E-Challenge highlights an incidental prebypass transesophageal echocardiographic (TEE) finding of a right atrial membrane that impacted cardiac surgical management during triple-valve surgery. Two-dimensional and advanced 3-dimensional (3D) TEE were used in real-time to assist intraoperative decision-making. The findings, clinical course, discussion of the differential diagnosis, final diagnosis, and patient management are detailed here. [ABSTRACT FROM AUTHOR]

Incidental findings are the radiographic findings detected in an asymptomatic or a symptomatic patient, these findings, however, are not correlated to the patient's clinical symptoms. Our objective was to report the prevalence of incidental findings, detected in digital panoramic radiographs, yet were not noted within the initial clinical examination of the patient attending the dental clinics at "Princess Nourah bint Adulrahman University (PNU)". All panoramic radiographs performed from April 2018 till March 2021 retrieved from the archives of the Axium Clinical and Practice Management Software database of the dental clinics at (PNU). A representative random sample of 400 out of 4010 panoramas were examined. All incidental radiographic findings were recorded and were categorized into five groups. About half of all examined panoramas had at least one incidental finding (46.8%). The most common incidental findings were idiopathic osteosclerosis (7.5%). Age of the patients was found to be significantly associated with the presence of at least one incidental finding. Incidental findings are common among patients in Saudi Arabia. This underscores the need for dental practitioners to examine the panoramic radiographs systematically and comprehensively for all patients, to make note of, record and properly manage these findings.

Germline pathogenic variants in E-cadherin (CDH1) confer high risk of developing lobular breast cancer and diffuse gastric cancer (DGC). The cumulative risk of DGC in CDH1 carriers has been recently reassessed (from 40–83% by age 80 to 25–42%) and varies according to the presence and number of gastric cancers in the family. As there is no accurate estimate of the risk of gastric cancer in families without DGC, the International Gastric Cancer Linkage Consortium recommendation is not straightforward: prophylactic gastrectomy or endoscopic surveillance should be proposed for these families. The inclusion of CDH1 in constitutional gene panels for hereditary breast and ovarian cancer and for gastrointestinal cancers, recommended by the French Genetic and Cancer Consortium in 2018 and 2020, leads to the identification of families with lobular cancer without DGC but also to incidental findings of pathogenic variants. Management of CDH1 carriers in case of incidental findings is complex and causes dilemmas for both patients and providers. We report eleven families (47 CDH1 carriers) from our oncogenetic department specialized in breast and ovarian cancer, including four incidental findings. We confirmed that six families did not have diffuse gastric cancer in their medical records. We discuss the management of the risk of diffuse gastric cancer in Hereditary Lobular Breast Cancer (HLBC) through a family of 11 CDH1 carriers where foci were identified in endoscopic surveillance. We also report a new colon signet ring cancer case in a CDH1 carrier, a rare aggressive cancer included in CDH1-related malignancies. [ABSTRACT FROM AUTHOR]

Conventional radiography is the mainstay for evaluation of developmental and pathologic disorders of oral and maxillofacial structures. Occasionally, clinicians may experience diagnostic pitfalls during interpretation of these imaging modalities. The aim of this article is to present 4 cases of pseudopathologic disorders found on intraoral and panoramic radiographs. Subsequent use of cone beam computed tomographic (CBCT) imaging determined that the initial concerning findings represented anatomical or radiographic anomalies rather than pathologic processes. Supplemental use of CBCT scans may enhance diagnostic assessment, possibly reducing the need for surgical intervention, and elucidate structurally compromised regions of the jaw that could predispose it to fracture.

In this paper, we describe a rare case of double aortic arch with dominant right arch with focal narrowing of the distal left arch and descendent aorta's dilatation, associated with pulmonary embolism and left subclavian steal syndrome, found in a 59-year-old woman with a history of dysphagia, chest discomfort, and left arm claudication. Diagnosis of this condition was made with a sub-optimal pulmonary CT-angiography with a combination of characteristic features of double aortic arch and vascular rings. Being aware of these conditions is crucial to avoid misclassification and surgical and endovascular complications.

Background: Malakoplakia is a rare disorder 75% of the reported cases affect mainly the genitourinary tract, its occurrence in the adrenal gland is extremely rare. Case presentation: A 65-year-old female patient presented to the emergency department for chronic abdominal pain. Radiographic and biochemical studies revealed a left adrenal incidentaloma and left adrenalectomy was performed. Histological examination showed the presence of Michaelis-Gutmann bodies, compatible with a malakoplakia of the adrenal gland. Conclusions: Malakoplakia is a rare disorder, with non-standardized treatment, medical and surgical therapies appear to be effective in treating the condition.

Calcifying pseudoneoplasm of the neuraxis (CAPNON) is thought to be a rare tumefactive lesion with unknown pathogenesis. Its prevalence is questionable with few previously reported cases of incidental CAPNON, and likely underdiagnosis. We report a unique case of incidental multifocal CAPNON. A 64-year-old female was admitted with loss of consciousness due to a ruptured right middle cerebral artery aneurysm with subarachnoid and intraventricular hemorrhage. She has a craniotomy and clipping. At time of operation, numerous small dural-based nodules were found, and one was excised for biopsy and was diagnosed as CAPNON. Retrospective review of her CT images identified nodules that were all ipsilateral to the ruptured aneurysm. A literature review revealed that incidental and/or multifocal CAPNONs are rare but likely underreported. Our case suggests a reactive process in the pathogenesis of CAPNON. [ABSTRACT FROM AUTHOR]

The harm associated with imaging abnormalities related to lung cancer screening (LCS) is not well documented, especially outside the clinical trial and academic setting. What is the frequency of invasive procedures and complications associated with a community based LCS program, including procedures for false-positive and benign, but clinically important, incidental findings? We performed a single-center retrospective study of an LCS program at a nonuniversity teaching hospital from 2016 through 2019 to identify invasive procedures prompted by LCS results, including their indication and complications. Among 2,003 LCS participants, 58 patients (2.9%) received a diagnosis of lung cancer and 71 patients (3.5%) received a diagnosis of any malignancy. Invasive procedures were performed 160 times in 103 participants (5.1%), including 1.7% of those without malignancy. Eight invasive procedures (0.4% of participants), including four surgeries (12% of diagnostic lung resections), were performed for false-positive lung nodules. Only 1% of Lung Imaging Reporting and Data System category 4A nodules that proved benign were subject to an invasive procedure. Among those without malignancy, an invasive procedure was performed in eight participants for extrapulmonary false-positive findings (0.4%) and in 19 participants (0.9%) to evaluate incidental findings considered benign but clinically important. Procedures for the latter indication resulted in treatment, change in management, or diagnosis in 79% of individuals. Invasive procedures in those without malignancy resulted in three complications (0.15%). Seventy nonsurgical procedures (6% complication rate) and 48 thoracic surgeries (4% major complication rate) were performed in those with malignancy. The use of invasive procedures to resolve false-positive findings was uncommon in the clinical practice of a nonuniversity LCS program that adhered to a nodule management algorithm and used a multidisciplinary approach. Incidental findings considered benign but clinically important resulted in invasive procedure rates that were similar to those for false-positive findings and frequently had clinical value.

Background and purpose: There is an absence of data from large population‐based cohort studies on the incidence of radiologically isolated syndrome (RIS). The incidence of RIS and the subsequent risk for multiple sclerosis (MS) were investigated. Methods: A population‐based, retrospective cohort study was conducted using a data‐lake‐based analysis of digitalized radiology reports. All brain and spinal cord magnetic resonance imaging (MRI) in people aged 16–70 during the years 2005–2010 (n = 102,224) were screened using optimized search terms to detect cases with RIS. The subjects with RIS were followed up until January 2022. Results: The cumulative incidence of RIS was 0.03% when all MRI modalities were included and 0.06% when only brain MRI was included according to MAGNIMS 2018 recommendation criteria. With the Okuda 2009 criteria, the respective figures were 0.03% and 0.05% (86% concordance). The overall risk for MS after RIS was similar, 32% by using the MAGNIMS and 32% by using the Okuda definition of RIS. Individuals aged <35.5 years exhibited the most significant predisposition to MS (80%), whilst those >35.5 years had less than 10% risk of MS. MS diagnosed after RIS constituted 0.8% of the incident MS cases in the population during 2005–2010. Conclusions: A population‐wide context was provided for the incidence of RIS and its relationship to MS. MAGNIMS recommendations were only slightly more sensitive to detect RIS compared to the Okuda criteria. RIS has a subtle effect on the overall incidence of MS, yet the risk for MS in individuals under the age of 35.5 years is substantial. [ABSTRACT FROM AUTHOR]

Simple Summary: Computed tomography (CT) is a commonly used imaging modality for the examination of the heads of rabbits and guinea pigs. This study reviewed 60 clinical records and CT examinations of the heads of rabbits and 65 of guinea pigs and investigated the incidental findings not directly related to the indications for the study and the suspected diagnoses. Most often, incidental findings involved the ears and the nose in both species. Mineralization in soft tissues is also often visible. The prevalence of incidental findings in CT examination of the analyzed species is high: 66.7% in rabbits and 64.6% in guinea pigs. (1) Background: Rabbits and guinea pigs are popular pet animals and often undergo computed tomography (CT) examination for assessment of pathologies of the head. The goal of the study was to review CT examinations of the heads of rabbits and guinea pigs to identify and classify incidental findings. (2) Methods: 60 CT studies of the heads of rabbits and 65 of guinea pigs presented at 2 Institutions were reviewed and the indications for the study recorded. (3) Results: The presence of CT findings not directly related to the reason for the CT examination was present in 40/60 (66.7%) studies of rabbits and in 42/65 (64.4%) studies of guinea pigs. Most commonly, the incidental findings involved the ears, in 24/60 studies in rabbits and in 29/65 studies in guinea pigs. Incidental findings involved the nasal cavities, respectively, in 9 and 7 rabbits and guinea pigs. Soft tissue mineralization was present in 11 rabbits and 17 guinea pigs. (4) Conclusions: Based on the present study, incidental findings detected on CT studies are often present in rabbits and guinea pigs. Veterinarians should be aware of the possible clinical impact of these findings. [ABSTRACT FROM AUTHOR]

Background: The incidental finding of thyroid inclusions in lymph nodes of neck dissections of non-thyroid cancer patients is an unusual event. It is still controversial for pathologists about whether this represents benign inclusions or metastatic papillary thyroid carcinoma (PTC). This study is to analyze clinicopathological features of such cases in an attempt to explore their clinical implications. Methods: Pathological data were searched for incidentally detected PTC of cervical lymph nodes in non-thyroid cancer cases. Clinicopathological characteristics were reevaluated and recorded. BRAF V600E protein expression and sequencing analysis was then performed in cases with sufficient tissues. Results: 31 patients had an incidental finding of PTC in lymph nodes of patients with non-thyroid cancer. BRAF immunohistochemical staining were performed in 17 metastatic lymph nodes with sufficient tumor tissues, and 6 were positive. BRAF V600E point mutation was detected in 5 of 6 BRAF V600E positive cases. Subsequent imaging examinations of the thyroid showed no nodules or calcifications/benign nodules in 20 patients, and suspected malignant nodules in 5 patients. 12 patients underwent total thyroidectomy or ipsilateral lobectomy, and 6 showed PTC in postoperative pathological examinations. The remaining 19 patients without surgery were kept under active surveillance, and no one had recurrence of PTC. Conclusion: Incidentally discovered PTC in lymph nodes has usually interpreted as metastasis from a clinical occult thyroid primary cancer, but primary PTC was not always detected. This suggests it could be double occult lesions. With regards to concurrence with highly malignant tumor, most patients could keep regular surveillance. [ABSTRACT FROM AUTHOR]

Inborn errors of immunity (IEI) include a variety of heterogeneous genetic disorders in which defects in the immune system lead to an increased susceptibility to infections and other complications. Accurate, prompt diagnosis of IEI is crucial for treatment plan and prognostication. In this study, clinical utility of clinical exome sequencing (CES) for diagnosis of IEI was evaluated. For 37 Korean patients with suspected symptoms, signs, or laboratory abnormalities associated with IEI, CES that covers 4,894 genes including genes related to IEI was performed. Their clinical diagnosis, clinical characteristics, family history of infection, and laboratory results, as well as detected variants, were reviewed. With CES, genetic diagnosis of IEI was made in 15 out of 37 patients (40.5%). Seventeen pathogenic variants were detected from IEI-related genes, BTK, UNC13D, STAT3, IL2RG, IL10RA, NRAS, SH2D1A, GATA2, TET2, PRF1, and UBA1, of which four variants were previously unreported. Among them, somatic causative variants were identified from GATA2, TET2, and UBA1. In addition, we identified two patients incidentally diagnosed IEI by CES, which was performed to diagnose other diseases of patients with unrecognized IEI. Taken together, these results demonstrate the utility of CES for the diagnosis of IEI, which contributes to accurate diagnosis and proper treatments. [ABSTRACT FROM AUTHOR]

Incidental pathology of the skull is frequently detected on cross sectional imaging of the brain. In contrast to the common finding of hyperostosis frontalis interna, biparietal bone thinning is less common. A case of an 87-year-old woman showing coexistence of hyperostosis frontalis interna and biparietal bone thinning is presented. This coexistence has not been reported previously.

Background: Modern CT scanners with lower radiation doses have resulted in large numbers of cardiac CTs being performed in children. As seen in adults, pediatric cardiac CT has the potential to demonstrate extracardiac variants and pathology that can occur in conjunction with congenital heart disease (CHD). Prior publications demonstrated a high incidence of extracardiac findings in various locations but the prevalence of urgent unexpected extracardiac findings in children is unknown. Objective: The purpose of this study was to describe the incidence, distribution and clinical significance of the extracardiac findings on pediatric cardiac CT at a tertiary referral center. Materials and methods: We reviewed all reports (n = 648) for 554 children through young adults who received a cardiac CT study between Jan. 2, 2018, and March 10, 2020, at our tertiary referral pediatric hospital. We interrogated CT reports for extracardiac findings and categorized them by system (airway, pulmonary, abdomen, malpositioned lines and musculoskeletal). We then subclassified each of these findings by level of clinical importance based upon the need for intervention or treatment into low, medium or high importance. High-importance findings were confirmed with a focused chart review. If a patient had more than one CT with a persistent extracardiac finding, the finding was only counted once. Results: We identified 562 individual extracardiac findings, with one or more extracardiac findings present in 91% of the study population. Extracardiac findings with high clinical importance, requiring urgent attention or intervention, were present in 10% (57/554) of cases. The most common location of extracardiac findings was pulmonary (50%; 280/562), followed by airway (22%; 125/562) and abdomen (9%; 52/562). Conclusion: Unexpected highly important extracardiac findings were found in 10% of patients. Therefore, extracardiac structures should be scrutinized for the timely identification of potentially highly important findings. [ABSTRACT FROM AUTHOR]

Abstract Background Extra-adrenal paraganglioma of the retroperitoneum is a very rare neoplasm arising from cells of the primitive neural crest. Although paragangliomas are considered benign and are often found incidentally, they have the potential to metastasize. Case presentation We report the case of a 68-year-old Caucasian woman with an incidental diagnosis of retroperitoneal paraganglioma that was discovered on chest computed tomography performed for high suspicion of coronavirus disease 2019 pneumonia. The patient showed no metastasis and was successfully treated by complete surgical removal of the tumor. Conclusion As the diagnosis of paragangliomas is often delayed because of absent clinical symptoms, they represent a significant diagnostic challenge. Although surgery may exacerbate coronavirus disease 2019 infection, surgical resection of this tumor is prioritized, given its malignancy potential, and it must be performed as soon as no infection is detected.

To report the concurrent presentation and management of IQCB1-associated Leber Congenital Amaurosis and NDP-associated Familial Exudative Vitreoretinopathy (FEVR). A 6-month-old Caucasian infant presented with poor visual response, high hypermetropia, and infantile-nystagmus with a provisional diagnosis of Leber Congenital Amaurosis based on clinical findings. Genetic counseling and testing were performed with a 285 gene retinal dystrophy panel (Blueprint Genetics). Clinical characteristics, presentation, ancillary testing results, and management are described. Two previously reported heterozygous pathogenic variants in ICQB1 were identified (c.1518_1519del (p.His506Glnfs*13) and c.1381C>T, p.Arg461*) segregating in trans. In addition, a variation of uncertain significance (VUS) was found in NDP (c.280C>T; p.His94Tyr). Fluorescein angiography was performed demonstrating peripheral avascularity and retinal telangiectasia without frank neovascularization. Peripheral ablative laser was applied to the avascular zone. The NDP VUS likely represents a pathogenic variant given the FEVR phenotype in addition to retinal degeneration, creating a rare dual phenotype. The combination of low oxygen demand from the IQCB1-associated retinal degeneration and NDP variant may have led to a more attenuated FEVR presentation with uncertain prognosis. A molecular diagnosis informed ocular and renal surveillance, as well as the recurrence risk for future offspring. [ABSTRACT FROM AUTHOR]

Root resorption is a destructive process that compromises tooth structure and can result in tooth loss. Often it remains asymptomatic and is an incidental finding on radiographic examinations. The purpose of this study was to determine prevalence and characteristics of root resorption in patients referred for cone-beam computed tomography (CBCT) imaging for a variety of indications. The study included CBCT scans of 1086 consecutive patients referred for CBCT imaging over an 18-month period. A total of 1148 scans were acquired. Data were abstracted from radiology reports, and prevalence estimates of resorption were computed for the aggregate sample and also across specific indications. Resorption was identified in 171 patients (15.7%, 95% CI: 13.6%–17.9%) and in 249 teeth with a prevalence range of 2.6%–92.3% across specific indications. An 18.7% of the patients had 2 resorption sites whereas 8.8% had 3 or more resorption sites. The majority of affected teeth were anteriors (43.8%), followed by molars (40.6%) and premolars (14.5%). The most prevalent resorption types were external (29.3%), cervical (22.5%), infection-induced apical resorption (13.7%), internal (9.6%), and impacted tooth induced (8.8%). The majority of teeth with resorption did not have prior endodontic treatment (73.9%) and had radiographically normal periapex (69.5%). Of 249 teeth with resorption, 31% presented as incidental finding. The prevalence of incidental findings of resorption increased with age, P <.05, and was significantly lower for anterior teeth (20.2%) as compared to premolars (41.7%) and molars (36.6%), (P <.05). The high proportion of incidental findings of resorption detected by CBCT suggests that resorption is not recognized/detected by conventional radiography and therefore remains underdiagnosed.

Objective:Incidental adnexal masses can be present during cesarean section and management options differ according to the properties of the mass. The objective of this study was to outline and discuss the clinical features and management of adnexal masses that were encountered during a cesarean section.Method:Records of 7,063 women who had cesarean section between November 2014 and December 2019 in a tertiary center were reviewed retrospectively. Sixty-four women who had an incidental adnexal mass and a pathology report were enrolled to this study.Results:The incidence of adnexal masses that detected at cesarean section was found as 0.9%. The pathologic diagnoses of the masses were as follows: The non-neoplastic group: Paratubal or paraovarian cyst (25 women, 39%), simple serous cyst (7 women, 11%) and corpus luteum cyst (4 women, 8%); the neoplastic group: Mature cystic teratoma (11 women, 17%), mucinous cystadenoma (5 women, 8%) and adenofibroma (3 women, 5%). All the women in the non-neoplastic group had undergone cystectomy. Sixteen of women (72%) in the neoplastic group had undergone cystectomy and 6 of them (28%) had undergone salpingo-oopherectomy. There was no perioperative and postoperative the complication in any of the patients.Conclusion:Surgical intervention in women who had incidental adnexal masses during cesarean section does not increase complication rate.
