To determine whether specific ultrasonographic features can predict failure of conservative treatment of acute appendicitis. A 2-year retrospective study was conducted on children admitted with acute appendicitis. Those with uncomplicated appendicitis diagnosed solely by ultrasound, and treated conservatively, were followed 18–24 m to assess treatment outcome. Management was considered successful if recurrent acute appendicitis was not observed during follow-up. Appendix diameter, wall thickness, presence of mucosal ulceration, hyperechogenic fat, free fluid, and lymph nodes were evaluated as potential discriminatory ultrasonographic predictors. T-tests, chi-square, sensitivity, specificity, and odds ratios were calculated. Out of 556 consecutive patients that were admitted with acute appendicitis, 180 (32%) managed conservatively. One hundred eleven (62%) imaged by US only. Ninety-two out of 111 (83%) were followed 18–24 m to assess treatment outcome, and 19/111 (17%) were lost to follow-up. Conservative management was successful in 72/92 (78.2%), with treatment failure in 20/92 (21.8%) (5/92 (5.4%) with recurrent acute appendicitis and 15/92 (16.3%) underwent appendectomy). Of the ultrasonographic features studied, mucosal ulceration demonstrated statistically significant predictive value. Fifteen out of 20 (75%) treatment failures had mucosal ulceration, compared to 21/72 (29.2%) of the patients with successful treatment (p

To determine whether imaging features and severity indices using low monoenergetic DECT images improve diagnostic conspicuity and outcome prediction in acute pancreatitis compared to conventional images. A retrospective study of patients with clinical and radiographic signs of acute pancreatitis who underwent 50 contrast-enhanced CT exams conducted on a single-source DECT was performed. Representative conventional and 50 keV-monoenergetic images were randomized and presented to four abdominal radiologists to determine preferred imaging for detecting fat stranding and parenchymal inflammation. Contrast and signal-to-noise ratios were constructed for necrotic, hypoattenuated, inflamed, and healthy parenchyma. These parameters and the CT severity index (CTSI) were compared between conventional and low monoenergetic images using paired t tests and correlated to clinical outcome. Although preference for conventional images was noted for subtle peri-pancreatic fat stranding (169/200 (85%) reads), there was clear preference for low monoenergetic images among all readers for pancreatic inflammation evaluation (188/200 (94%) reads). Moreover, identification of small, hypoattenuating inflammatory foci on monoenergetic images alone in 13/50 (26%) cases resulted in upstaged CTSI from mild to moderate in 7/50 (14%), associated with longer hospitalization (16 ± 17 days vs. 5 ± 2 days; p < 0.05), ICU admission, and drainage. Quantitatively, a twofold difference between normal and inflamed parenchyma attenuation was identified for monoenergetic (44.8 ± 27.6) vs. conventional (25.1 ± 14.7) images (p < 0.05). Significant increases were seen in the monoenergetic SNR and CNR compared to the conventional images (p < 0.05). DECT low monoenergetic images afford better tissue assessment and demarcation of inflamed pancreatic parenchyma. Additionally, they provide improved characterization of the extent parenchymal necrosis, enabling better classification that may better predict severe clinical outcomes. • DECT low monoenergetic images afford better tissue assessment and demarcation of inflamed pancreatic parenchyma and provide improved characterization of the extent parenchymal necrosis. • Qualitatively, low monoenergetic images were preferred over conventional DECT images for the evaluation of pancreatic inflammation; and quantitatively, there is a twofold difference between normal and inflamed parenchyma attenuation, SNR, and CNR between monoenergetic vs. conventional images. • Monoenergetic imaging identified additional small, hypoattenuating inflammatory foci in 26% resulting in an upstaged CT severity index in 14% associated with longer hospitalization, ICU admission, and drainage, thereby enabling better classification and better prediction of severe clinical outcomes.

Early recurrent ileocolic intussusception (RICI) is a rare event. We aimed to estimate the rate of RICI and identify predisposing factors for early recurrence for children treated in a tertiary-care academic medical center. Consecutive children who were diagnosed with ileocolic intussusception (ICI) during the years 2005–2015 and had successful enema reduction were included. Demographic, clinical, imaging, and laboratory data were recorded for analysis. Ultrasound and fluoroscopy images were reviewed. Early RICI was defined as recurrence within 48 h. Two hundred forty-five episodes of intussusception in 210 patients, ages 2 to 77 months (mean 12.7), were included. Six patients (2.45%) had a RICI between 7 and 28 h (mean 17 h) after initial successful reduction. A total of 5/6 recurrences (83.3%) were in winter months. In the group without early recurrence, only 19.6% of the cases presented during the winter (p = 0.001). Mean age in the early recurrence group was 23 months compared to 12.4 months children with no early recurrence (p = 0.016). All other analyzed parameters were comparable for the groups. Early RICI is a relatively rare event that may not justify routine admission and long observation. The approach should be individual, based on the clinical picture.

A patient developed hemopericardium shortly after left brachial arterial embolectomy using an embolectomy catheter. Evaluation disclosed evolving pseudoaneurysm of the right coronary artery that was successfully managed by stenting. Misplacement of the embolectomy catheter within the coronary vessel was facilitated by an anomalous origin of the right coronary artery. This complication highlights the importance of correct insertion of the embolectomy catheter using the markers to avoid maladvancement and damage to central vessels.

Objective: Bone density loss and increased risk for osteoporosis are of concern in Hodgkin lymphoma (HL) patients. Routinely performed positron emission tomography-computed tomography (PET-CT) scans could be informative in assessing bone mineral density (BMD). Methods: This retrospective study included 80 adults with newly diagnosed HL treated with standard first-line chemotherapy regimens. PET-CT scans performed at diagnosis (PET-CT1), at the end of chemotherapy (PET-CT2), and at follow-up after remission (PET-CT3) were used to assess BMD changes by measuring lumbar vertebrae CT attenuation. A CT attenuation threshold of 160 Hounsfield units was used to define abnormal BMD. Results: Following chemotherapy, comparison of PET-CT2 with PET-CT1 revealed a mean (standard deviation) 14.2% (10.4%) BMD reduction (P

Purpose We aimed define thresholds for HU values observed on opportunistic CT scans that suggest abnormal bone mineral density (BMD) in a heterogeneous Middle Eastern population. Methods Consecutive patients who had undergone CT and dual-energy X-ray absorptiometry (DXA) test of the lumbar spine within 6 months were included in this retrospective study. Hounsfield units (HU) on lateral lumbar spine CT and BMD at the spine and hip on DXA were compared. Potential HU thresholds suggestive of abnormal BMD were established using receiver operating characteristic (ROC) analysis. Results 246 patients (mean age of 64 ± 11.6 years; 83 % female) were included. On DXA, 27 % had osteoporosis, 56 % had osteopenia, and 17 % had normal BMD. To distinguish osteoporosis from non-osteoporosis (osteopenia, normal BMD), a threshold of HU160 had sensitivity 95 % and the balanced threshold was HU121 (sensitivity 74 %, specificity 61 %). To distinguish normal from abnormal BMD (osteoporosis, osteopenia), a threshold of HU110 had specificity 93 % and the balanced threshold was HU149 (sensitivity 76 %, specificity 74 %). Conclusions In a heterogeneous Middle-Eastern population, our study supports the reported correlation between HU values on lumbar spine CT and BMD on DXA. In this population, HU > 160 correlates with low probability of osteoporosis on DXA, and screening examination is not warranted unless a vertebral fracture is detected; for HU ≤ 110 there is high probability of abnormal (osteoporosis or osteopenia) BMD, DXA examination is warranted; Finally, for HU 110–160, there is an intermediate chance of abnormal BMD, DXA examination may be warranted in specific patients with other risk factors.

Purpose To evaluate radiological findings in a cohort of 22 patients with infantile malignant osteopetrosis in order to establish the correlation between radiological findings and different genetic backgrounds. Materials and Methods Clinical files, genetic analysis results, and radiological examinations of children treated for osteopetrosis with bone marrow transplantation in a referral center in the last 5 years were retrospectively evaluated. The study received institutional review board (IRB) approval. Results Twenty-two patients were included in the study: 18 males, four females, ages 1 month–9 years 10 months, and the median age was 11 months (mean 23 months). There were 12 patients with different mutations in the TCIRG1 gene, five with mutations in the SNX10 gene, four children harbored RANK mutations, and one patient had a CLCN7 mutation. We noted more severe radiological findings in patients with TCIRG1 and RANK mutations, including fractures, osteopetrorickets, hydrocephalus, and hepatomegaly. Varus deformity of the femoral neck was seen exclusively in patients with a TCIRG1 mutation. Conclusions The variable genetic spectrum of osteopetrosis is associated with a variable radiological presentation. These correlations may be helpful for priorities in genetic analysis.

We assessed the clinical value of repeat spine CT scan in 108 patients aged 18-60 years who underwent repeat lumbar spine CT scan for low back pain or radiculopathy from January 2008 to December 2010. Patients with a neoplasm or symptoms suggesting underlying disease were excluded from the study. Clinical data was retrospectively reviewed. Index examinations and repeat CT scan performed at a mean of 24.3 ± 11.3 months later were compared by a senior musculoskeletal radiologist. Disc abnormalities (herniation, sequestration, bulge), spinal stenosis, disc space narrowing, and bony changes (osteophytes, fractures, other changes) were documented. Indications for CT scan were low back pain (60 patients, 55%), radiculopathy (46 patients, 43%), or nonspecific back pain (two patients, 2%). A total of 292 spine pathologies were identified in 98 patients (90.7%); in 10 patients (9.3%) no spine pathology was seen on index or repeat CT scan. At repeat CT scan, 269/292 pathologies were unchanged (92.1%); 10/292 improved (3.4%), 8/292 worsened (2.8%, disc herniation or spinal stenosis), and five new pathologies were identified. No substantial therapeutic change was required in patients with worsened or new pathology. Added diagnostic value from repeat CT scan performed within 2-3 years was rare in patients suffering chronic or recurrent low back pain or radiculopathy, suggesting that repeat CT scan should be considered only in patients with progressive neurologic deficits, new neurologic complaints, or signs implying serious underlying conditions.

To assess the diagnostic value of ultrasound compared to CT in evaluating acute abdominal pain of different causes in children 10 years of age and under, hospital records and imaging files of 4052 patients under age of 10 who had imaging for abdominal pain were reviewed. One-hundred-thirty-two patients (3 %), (74 males/58 females) who underwent ultrasound and CT within 24 h were divided by age: group I, ages 0–48 months (25 patients); group II, 49–84 months (53 patients); and group III, 85–120 months (54 patients). Diagnoses at ultrasound, CT, and discharge were compared. Cases of a change in diagnosis following CT and impact of the changed diagnosis on patient management were assessed. Non-diagnostic ultrasound or a diagnostic conundrum was present in a small percentage (3 %) of our patients. In the group of patients imaged with two modalities, CT changed the diagnosis in 73/132 patients (55.3 %). Patient management changed in 63/132 patients (47.7 %). CT changed the diagnosis in 46/64 patients with surgical conditions (71.8 %, p

Worldwide use of synthetic cannabinoids (SCs) is rapidly increasing, in part due to the generation of numerous new compounds, sidestepping legal restrictions. Their detection using standard toxicology panels is difficult, due to their vast heterogeneity and lack of structural resemblance to cannabinoids. Sympathetic overactivity and arterial spasm play a role in some of the life-threatening reactions to SCs, such as coronary or cerebral vasoconstriction. Here we report a patient with repeated consumption of SCs that led to mesenteric ischemia and death. A 29-year-old man was frequently evaluated in the Emergency Medicine Department for recurrent transient crampy abdominal pain, associated with the use of the SCs colloquially known as “Mr. Nice Guy.” He was finally hospitalized with a protracted attack, associated with diarrhea and leukocytosis. Initial evaluation including computed tomography was unremarkable. Diarrhea and leukocytosis gradually resolved, but bouts of hypertension and abdominal pain occurred in association with repeated consumption of the SCs. On the fifth hospital day, the patient developed abrupt abdominal pain, associated with profound shock and signs of peritoneal irritation and succumbed within an hour. Postmortem CT scan was consistent with intestinal perforation most probably due to a nonobstructive mesenteric infarction. There was no evidence of a single vessel infarction.

Traditionally, patients treated conservatively for periappendiceal abscess or phlegmon would subsequently undergo interval appendectomy (IA); however, recent evidence has shed doubt on the necessity of this procedure. This study aimed to assess the outcomes of patients who underwent IA, in comparison with those operated acutely for appendicitis.A retrospective analysis identified patients who underwent IA between 2000 and 2016. Their course and outcomes were compared with those of our previously published cohort of patients who underwent appendectomy for acute appendicitis.During the study period, 106 patients underwent IA. Their mean age was 39.7 ± 16.2 y, and 60.4% were females. In their index admission, 75.5% presented with abscesses. IA was performed successfully in all patients, and no patient required colectomy. Pathology demonstrated neoplastic lesions in 6/106, but only one was malignant. IA patients were compared with a cohort of 1649 acute appendectomy patients. This group was significantly younger (33.7 ± 13.3 y). Operation time was comparable between the groups (46.0 ± 26.2 versus 42.7 ± 20.9 min, respectively, P = 0.33). In the IA group, significantly more laparoscopic operations were performed (100% versus 93.9%), but with a higher conversion rate to open (1.9% versus 0.13%, P 0.001). Although the overall complication rate was comparable, more intraoperative complications (2.8% versus 0.3%, P 0.001) and deep/organ-space surgical site infections (surgical site infection; 4.7% versus 1.2%, P = 0.003) were reported in the IA group.IA can be a challenging procedure and should not be performed on a routine basis. However, neoplasia must be actively ruled out, particularly in the older age group.

Background Airway infections in Primary Ciliary Dyskinesia (PCD) are caused by different microorganisms, including pseudomonas aeruginosa (PA). The aim of this study was to investigate the association of PA colonization and the progression of lung disease in PCD. Methods Data from 11PCD centers were retrospectively collected from 2008 to 2013. Patients were considered colonized if PA grew on at least two separate sputum cultures; otherwise, they were classified as non-colonized . These two groups were compared on the lung function computed tomography (CT) Brody score and other clinical parameters. Results Data were available from 217 patients; 60 (27.6%) of whom were assigned to the colonized group. Patients colonized with PA were older and were diagnosed at a later age. Baseline forced expiratory volume at 1 s (FEV 1 ) was lower in the colonized group (72.4 ± 22.0 vs. 80.1 ± 18.9, % predicted, p = 0.015), but FEV 1 declined throughout the study period was similar in both groups. The colonized group had significantly worse CT-Brody scores (36.07 ± 24.38 vs. 25.56 ± 24.2, p = 0.034). A subgroup analysis with more stringent definitions of colonization revealed similar results. Conclusions Lung PA colonization in PCD is associated with more severe disease as shown by the FEV 1 and CT score. However, the magnitude of decline in pulmonary function was similar in colonized and non-colonized PCD patients.

Behçet's disease (BD) is a chronic multisystemic inflammatory disorder. Cardiac abnormalities including intracardiac thrombi have been described in up to 16% of cases. The clinical presentation of cardiac complications in BD may include fever, dyspnea, chest pain, hemoptysis, and edema. We present 2 cases of patients who underwent surgical excision of intracardiac masses thought to be intracardiac malignancies. Further pathological and clinical evaluation established intracardiac inflammatory masses due to BD as the final diagnosis. As intracardiac masses may be the presenting manifestation of BD, it is crucial for echocardiographers to consider BD in the differential diagnosis. A careful history and physical exam looking for signs and symptoms of BD is critical before considering surgical excision of unexplained intracardiac masses. If the final diagnosis is BD anti-inflammatory therapy should be considered the basis of treatment.

Background Impaired mucociliary clearance causes pulmonary disease in primary ciliary dyskinesia (PCD) and contributes to cystic fibrosis (CF) lung disease. Although the sinopulmonary disease is similar, morbidity and mortality are different. Both patients with PCD and patients with CF with pancreatic sufficiency (CF-PS) show no nutrient malabsorption and are diagnosed at a later age compared with patients with CF with pancreatic insufficiency (CF-PI). Methods Clinical status, microbiology, FEV1, and high-resolution CT (HRCT) scans presented as total Brody score (CT-TBS) were compared for patients with PCD, CF-PI, and CF-PS, all treated at the same medical center, by the same team, and by a similar routine follow-up. Results One hundred sixty-four patients, 34 with PCD, 88 with CF-PI, and 42 with CF-PS were enrolled. PCD was diagnosed at a similar age as CF-PS but significantly later than CF-PI. Mean FEV1 % predicted was similar for the three groups. The rate of FEV1 change with age in PCD was similar to CF-PS but significantly lower than in CF-PI. Severity of structural lung disease (CT-TBS) was similar for PCD and CF-PS and significantly higher in CF-PI. No correlation between TBS or Pseudomonas aeruginosa infection and FEV1 in PCD was seen, whereas a negative correlation with FEV1 was observed for both CF groups. Conclusions Although in our study PCD was similar to CF-PS, the lack of correlation between FEV1 and age, CT-TBS, and P aeruginosa infection in PCD suggests that impaired mucociliary clearance is not the only cause for inducing pulmonary damage in these diseases. Furthermore, a comparison of disease characteristics for PCD and CF should distinguish between CF-PI and CF-PS as different entities.

Study design Retrospective. Objective To assess radiation exposure time during robot-guided vertebral body augmentation compared with other published findings. Summary of background data Rising incidence of vertebral compression fractures in the aging population result in widespread use of vertebral body cement augmentation with significant radiation exposure to the surgeon, operating room staff, and patient. Radiation exposure leads to higher cancer rates among orthopedic and spine surgeons and patients. Methods Thirty-three patients with 60 vertebral compression fractures underwent robot-guided vertebral body augmentation performed by 2 surgeons simultaneously injecting cement at 2 levels under pulsed fluoroscopy. The age of patients was in the range from 29 to 92 (mean, 67 yr). One to 6 vertebrae were augmented per case (average 2). Twenty-five patients had osteoporotic fractures and 8 had pathological fractures. Robotic guidance data included execution rate, accuracy of guidance, total surgical time, and time required for robotic guidance. Radiation-related data included the average preoperative computed tomographic effective dose, radiation time for calibration, registration, placement of Kirschner wires, and total procedure radiation time. Radiation time per level and surgeon's exposure were calculated. Results Kyphoplasty was performed in 15 patients (1 sacroplasty), vertebroplasty in 13, and intravertebral expanding implants in 5. The average preoperative computed tomographic effective dose was 50 mSv (18-81). Average operative time was 118 minutes (49-350). Mean robotic guidance took 36 minutes. Average operative radiation time was 46.1 seconds per level (33-160). Average exposure time of the surgeons and the operating room staff per augmented level was 37.6 seconds. The execution rate was 99%, with an accuracy of 99%. Two complications (hemothorax and superficial wound infection) occurred. Conclusion The radiation exposure of the surgeon and the operating room staff in a series of robot-assisted vertebral body augmentation was 74% lower than published results on fluoroscopy guidance and approximately 50% lower than the literature on navigated augmentation. Level of evidence 4.

PURPOSE Pulmonary hypertension (PHTN) is a significant cause of morbidity and mortality in patients with cystic fibrosis (CF), but a routine noninvasive test for evaluating PHTN is lacking. We aimed to determine whether there is a correlation between computed tomography (CT) signs for PHTN and lung disease severity in CF. MATERIALS AND METHODS We retrospectively evaluated high-resolution CT studies of 91 consecutive CF patients. The ratios of the widest diameters of the main pulmonary artery (MPA), right pulmonary artery, and left pulmonary artery to the ascending aorta (Ao) were calculated. MPA/Ao>1 was considered indicative for PHTN. Lung severity was assessed with modified Brody scores for the left lung (LL), right lung (RL), and overall [Total Brody Score (TBS)]. The nonparametric Pearson χ test was performed for determining the correlation between Brody score and objective CT signs for PHTN. RESULTS This study included 54 male and 37 female patients aged between 3 and 67 years (mean 17.6 y). Mean RL, LL, and TBS were 23.71, 23.31, and 47.15, respectively. Of the 91 patients, 28 (30.8%) had MPA/Ao>1, indicating a high probability for PHTN. Among these patients, the mean TBS was 38.8, as compared to mean of 50.8 in 63 patients with MPA/Ao≤1. No correlation was found for the RL and LL separately. CONCLUSION There was no correlation between parenchymal lung disease severity assessed by the modified Brody score and CT signs of PHTN in CF patients.

Background Cystic fibrosis (CF) genotypes characterized by pancreatic sufficiency (PS) are generally associated with milder disease vs genotypes characterized by pancreatic insufficiency (PI); however, the correlation between pancreatic status and type and severity of structural lung changes has not been studied. We aimed to evaluate differences in the severity and distribution of pulmonary manifestations of CF in patients with PS vs PI. Methods We retrospectively evaluated changes in individual lobes and the whole lung on chest CT scan with the modified Brody score. The study population included 84 (39 female, 45 male) patients with CF aged 4 to 68 years (mean, 20.5) treated from 2000 to 2010. Our institutional review board waived the requirement for informed consent. The severity of lung changes and distribution of pulmonary disease were compared by Student t test, nonparametric Pearson χ 2 test, or mixed-design analysis of variance for 28 patients with CF-PS and 56 with CF-PI. Correlations were evaluated with the Pearson (continuous variables) or Spearman ρ (nonparametric variables) tests. A linear regression model was used for multivariate analyses. Results Compared with patients with CF-PS, those with CF-PI had more-severe lung disease ( P = .001) with predominant upper lobe involvement ( P = .002) and significant differences in Brody scores for bronchiectasis and bronchial wall thickening. Lung manifestations in patients with CF-PS did not show predominant involvement of any one area ( P = .133). Conclusions In patients with CF-PI, structural lung changes are more severe with upper lobe predominance, prominent bronchiectasis, and bronchial wall thickening vs lower severity and more general distribution of changes in those with CF-PS.

Spinal dural arteriovenous fistulas (SDAVFs) are the most common spinal vascular malformations and can be a significant cause of myelopathy although they are under diagnosed. Surgical or embolization treatment of SDAVFs improved significantly in the last decade. However, a high percentage of patients are still left with severe disability.To describe the correlation between time to diagnosis and the rehabilitation outcomes of eight patients with SDAVFs.Retrospective chart study of all SDAVF patients in 20 years.A tertiary university rehabilitation center.The lower extremities motor score (LEMS), Functional Independence Measure (FIM), Spinal Cord Independence Measure (SCIM) and Walking Scale for Spinal Cord Injury (WISC II). Overall prognosis was evaluated using the Aminoff-Logue scale (ALS).There were seven men and one woman with mean age of 61.3 ± 15 (30-72) and mean time until the diagnosis of SDAVF of 265.5 ± 245 days (4-730). At the end of rehabilitation period, five of the eight patients remained wheelchair dependent. Strong correlation was found between LEMS, FIM, SCIM, and WISC II scores and the functional level according to the ALS scale. A significant correlation was found between time to diagnosis and the height of the SDAVF, the clinical and rehabilitation outcomes. Patients with high SDAVF which were diagnosed late had the poorest prognosis.The potential for functional ambulation in patients with SDAVF is related to the time of intervention. This finding emphasizes the important of early diagnosis and early intervention in SDAVF.

Background The thymus changes with age. Its shape and the proportion of solid tissue and fat vary between individuals, yet there is no comprehensive work describing the size and morphology of the normal thymus on CT. As a result, many adults with some preserved soft tissue in the thymus may undergo extensive work-up to exclude mediastinal tumor. Our aim was to quantify CT characteristics of the normal thymus in an adult population. Methods CT chest scans of 194 trauma patients aged 14–78 years (mean 52.6 years), were retrospectively reviewed. The density, volume, shape and predominant side of the thymus were recorded for 56 patients in whom some solid tissue was preserved. Statistical analysis of these characteristics according to the patient age and gender was performed. Results Thymic density and volume decreased progressively with age. No solid tissue component was seen in the thymus in patients older than 54 years. In the majority of patients, the thymus had an arrowhead shape, with middle position. However, great variability in thymic shape and border were noted. There was a highly significant relationship between density and patient age ( p Conclusion We hope that our work will help in the definition of normal thymic CT parameters in adults, help to prevent unnecessary and expensive imaging procedures, and reduce patient exposure to ionizing radiation.

Purpose To assess correlations between stone size/location and severity of secondary signs for ureteral obstruction. Methods Unenhanced multi-detector computed tomography examinations of 150 patients with acute renal colic were reviewed. Stone size, location in the ureter, kidney size and Hounsfield unit values, perinephric edema, and degree of hydronephrosis were assessed. Results Pale kidney sign was detected in 36%. Hydronephrosis was mild in 63% and severe in 21%; severe hydronephrosis was associated with larger stones. Mid-ureter and ureteropelvic junction stones were more likely to cause hydronephrosis. Perinephric edema (56%) was not correlated with stone size/location. Conclusion Only severe hydronephrosis was significantly associated with larger stone size.

Free intraperitoneal fluid can be an important sign in an abdominal inflammatory process or abdominal trauma. It is often present in children with abdominal pain, but it is a nonspecific finding. A minimal amount of free intraperitoneal fluid is considered normal.The purpose of this study was to evaluate the incidence, location and volume of free fluid in the abdomen and pelvis in a population of asymptomatic children.In this prospective study, we performed clinically indicated abdominal and pelvic sonography, using high-resolution transducers, in 200 asymptomatic children: 104 (52%) girls, 96 (48%) boys; ages 6 days-15 years (mean 3 years 8 months). US studies were performed and prospectively evaluated by two experienced pediatric radiologists. Patients with any condition that could result in the accumulation of free intraperitoneal fluid as well as postpubertal girls were excluded from the study.Free intraperitoneal fluid was seen in 12 children (6%), only in the pelvis. Fluid volume never exceeded 1 ml.Our study suggests that 1 ml or less of free intraperitoneal fluid detected in the pelvis is probably insignificant.

Background. Calcifications in arteries are thought to represent atherosclerosis. Methods. Consecutive abdominal tomographic scans performed during a 4-month period were evaluated and assessed for renal artery calcifications (RAC). Scans that showed calcifications were evaluated for renal artery narrowing and for various characteristics of the atherosclerotic plaque. Results. Of 350 consecutive examinees, 43% were men, 40% had hypertension and 38% had hypercholesterolaemia. The age was 61 ± 13 years. Aortic calcifications were found in 54% and RAC in 102 (29%), of whom 53 had bilateral calcifications. Subjects with RAC were older, 72 ± 6v ersus 55± 12 years. Adjusted odds ratios of RAC were 2.2 (95% CI 1.1–4.6) for male gender, 2.4 (1.2–4.8) for hypertension and 2.9 (1.4–5.8) for hypercholesterolaemia, whereas family history of hypertension was protective with 0.5 (0.3–0.9). All patients with calcified renal arteries had aortic calcifications, versus 35% of those without RAC. A significant correlation was found between the severity of calcifications and the degree of renal artery narrowing (r = 0.7), and also between the presence of bilateral calcifications and a high-grade narrowing. Conclusions. RAC strongly relates to atherosclerosis. Calcifications and artery narrowing may have a role in the pathogenesis of hypertension. Bilateral calcifications suggest atherosclerotic renal artery stenosis.

To evaluate the diagnostic possibilities of CT virtual pneumoendoscopy, in various vesical and extra-vesical urinary tract abnormalities and suggest possible indications for this examination. Thirty-three patients (26 men and 7 women, aged 30–91, mean-61 years) were referred by the urologists for specific further evaluation of the urinary tract with virtual pneumoendoscopy for various indications. All patients except three underwent conventional endoscopy within a week either before or after the virtual examination, but the endoscopy was either equivocal or limited. The urinary tract was insufflated with room air. Successful CT pneumoendoscopy was achieved in 31 of the 33 patients. The indications for the virtual study included obstructive uropathy (22), hematuria (15), and suspected fistula (2). The virtual examination findings included urethral stricture, recto-urethral fistula, multiple bladder tumors, bladder tumor invading the distal ureter or urethra, bladder diverticula containing a tumor, ureteral stricture, renal transitional cell carcinoma, and renal calculi with inflammation. Virtual CT endoscopy had added value to the diagnostic process in all our patients. In selected cases virtual CT pneumoendoscopy may serve as an important adjunctive diagnostic aid for urologic pathologies.

OBJECTIVE. Adnexal torsion is most commonly a clinical diagnosis, often aided by sonographic findings. At times, the clinical presentation can mimic nongynecologic causes of acute lower abdominal pain. In these cases, CT may be the initial imaging study. The purpose of this study was to define the CT features associated with adnexal torsion.CONCLUSION. On CT, a well-defined adnexal mass abnormally located in the pelvis with ipsilateral deviation of the uterus in a woman or girl with lower abdominal pain should raise the suspicion of adnexal torsion. Inflammatory signs on CT suggest the presence of necrosis.

To investigate which clinical, laboratory, and CT findings potentially facilitate the differential diagnosis between tubo-ovarian abscess (TOA) and periappendicular abscess (PAA), we retrospectively reviewed abdominal CT examinations and medical records for all women who presented to our medical center with unilateral right pelvic abscess formation who underwent CT evaluation from 2004-2014. A wide spectrum of clinical data and imaging findings were recorded. CT diagnoses were made in consensus by two experienced body radiologists blinded to the final diagnosis. Findings associated with the infections were compared using the chi-square (χ(2)) or the Fisher exact test. Ninety-one patients were included; 58 with PAA (mean age 46 years) and 33 with TOA (mean age 37 years). Pain on cervical motion (67 %) and vaginal discharge (21 %) were significantly more common in TOA; other clinical signs were similar. The presence of right ovarian vein entering the mass on CT had 100 % specificity and 94 % sensitivity to TOA. Distended right fallopian tube (79 %), mass posterior to mesovarium (76 %), contralateral pelvic fat stranding (55 %), and thickening of sacrouterine ligaments (55 %) were significantly more common in TOA. Positive "arrowhead sign" (91 %), mesenteric lymphadenopathy (85 %), small bowel wall thickening (55 %), fluid in the right paracolic gutter (50 %), and cecal wall thickening (48 %) were significantly more common in PAA;internal gas was revealed only in PAA (33 %). Distinct CT features can increase diagnostic certainty regarding the origin of right lower quadrant abscess in women.

Renal vein thrombosis and membranous glomerulopathy in a patient homozygote for factor V Leiden mutation: A mere coincidence?

Behçet disease is a multisystemic and chronic inflammatory disorder of unknown cause that is characterized by recurrent oral and genital ulcerations, ocular manifestations, and additional clinical manifestations in multiple organ systems. Behçet disease involving the chest can manifest as a wide spectrum of abnormalities. Although conventional chest radiography is commonly used for initial assessment, spiral computed tomography can demonstrate the entire spectrum of thoracic manifestations of Behçet disease, including abnormalities of the vessel lumen and wall, perivascular tissues, lung parenchyma, pleura, and mediastinal structures. Aneurysms of the pulmonary arteries, with or without thrombosis, are a typical manifestation of Behçet disease. Other manifestations include thrombosis, vasculitis, hemorrhage, infarction, and inflammation. Familiarity with these manifestations can be useful in the diagnosis of Behçet disease, helping to determine the cause of symptoms in patients who present with hemoptysis and guide the choice of appropriate therapy.

SummaryThrombosis of the ovarian vein is a remarkable process occuring within a few days of labor in 1:500-1:2000 women. Its presentation is characterized by fever, abdominal pain and occasionally by a palpable abdominal mass that in earlier years sometimes lead to explorative laparotomy. With the advent of modern imaging techniques the diagnosis can be made relatively easily. The pathogenesis has been attributed to an infectious process expanding from the uterus to the right ovarian vein and stasis. A predisposition towards thrombosis has not been so far explored. In this study we retrospectively analysed the clinical features, diagnosis and treatment of 22 patients with objective documentation of post partum ovarian vein thrombosis (POVT) and assessed potential risk factors. In 11 of the 22 patients (50%) inherited prothrombotic risk factors were detected as follows: 4 were heterozygous for factor V G1691 A, 2 had protein S deficiency, one had protein S deficiency and was heterozygous for factor V G1691A, and 4 were homozygous for MTHFR C677T. Eight of the 11 patients who bore a prothrombotic predisposition underwent cesarean section. Taken together, the data suggest that POVT may result from the combined effect of an infection, cesarean section and a prothrombotic tendency.

A 20-year-old man with Behcet's disease characterized by recurrent arterial aneurysms presented with a new aortic root aneurysm. This patient previously had aneurysms of the coronary arteries and vein, as well as ruptured renal artery aneurysm. Chronic maintenance immunosuppressive therapy was recommended due to the catastrophic nature of the disease, which the patient refused to take. The patient died shortly after admission. This case demonstrates the unique catastrophic natural history of vascular Behcet's disease with recurrent life-threatening arterial events, and this case stresses the therapeutic dilemma of maintenance immunosuppressive therapy in selected patients.

Torsion of an accessory spleen is extremely rare. We report a case of an acute torsion of an accessory spleen in a young patient who presented with acute left abdominal pain and discuss the computed tomographic findings of this exceptional condition. Awareness of this entity and familiarity with typical imaging findings are mandatory for preoperative diagnosis.

Here we present an unusual case of anaplastic lymphoma kinase positive anaplastic large cell lymphoma (ALCL), appearing as a primary tumor of the pancreas which invaded into the adjacent duodenal wall, causing upper gastrointestinal bleeding. After complete resection of the tumor (Whipple's operation), the patient received 4 cycles of CHOP chemotherapy. Currently, 2 years after diagnosis the patient still remains lymphoma free. Primary ALCL of the pancreas is very rare and has only been reported on one previous occasion. Nevertheless, lymphoma should be considered in the differential diagnosis of pancreatic tumors and an attempt to obtain tissue diagnosis is always necessary before continuing with radical surgery, especially in young patients.

Background context Spinal dural arteriovenous fistula (SDAVF) is a slow-flow extramedullary vascular lesion affecting primarily the lower thoracic and lumbar spine. The clinical sequela of these vascular changes is progressive myelopathy and severe lower-extremity weakness. Although surgical or embolic treatment of SDAVFs has improved significantly in the last years, the ambiguity of the symptoms may complicate and delay the diagnosis. The influence of the postponed diagnosis on the functional outcome of patients with SDAVF is unknown. Purpose To describe a case series of patients with SDAVF that illustrates that delayed diagnosis leads to grave neurologic and functional prognosis. Study design A case series. Methods We present a series of seven patients, treated in a tertiary university rehabilitation center over 20 years. Clinical, radiologic, and functional outcomes were evaluated by retrospective chart review. Neurologic and functional evaluation at the end of rehabilitation was evaluated with the lower extremities motor score and the Aminoff-Logue scale, respectively. Results All our patients were men with a mean age of 60.3±16 years (30–72 years), mean time until the diagnosis of SDAVF was 302.8±239 days (60–730 days), and mean overall length of stay in acute department and rehabilitation unit was 88.6±34 days (46–149 days). At the end of rehabilitation period, four patients remained at wheelchair level with an Aminoff-Logue scale grading of five whereas other functional scales showed also low levels of recovery. Conclusions Our series showed that the potential for functional ambulation was poor despite prolonged rehabilitation treatment in late diagnosis SDAVF. Awareness of the early symptoms of SDAVF and immediate intervention may help reduce impairment in such patients.

Objective To describe the normal computed tomography (CT) appearance of the pelvis after uncomplicated Cesarean section (C-section). Patients and methods Pelvic CT examinations of 31 patients after uncomplicated C-section were reviewed. Results Higher postoperative day (POD) correlated well with decreases in the uterine long axis and endometrial width but did not correlate to scar width. Full thickness defect of the uterine wall was revealed in 48% of patients. Small volumes of intrauterine gas presented in half of patients at POD 1–26. Free pelvic fluid appeared in 74%. Pelvic collections were rare and small. Conclusion There is wide variability in pelvic CT appearance following uncomplicated C-section.

Purpose To describe the spectrum of radiological findings in 12 patients with H syndrome. Patients and Methods Various radiological examinations of 12 patients (M=9, F=3) with H syndrome were reviewed. Results Symmetrical thickening of the skin of the subcutaneous tissue at the lower half of the body (n=9, 75%), with retracted micropenis in males (n=5, 55%). Groin varices (n=5, 42%) and lymphadenopathy (n=5, 42%) were observed in severe cases. Severe symmetrical flexion deformities of the fingers (n=7, 58%) were relatively common. Conclusion Skin thickening with subcutaneous fat infiltration and deformities of the hands and feet are typical for H syndrome.

Background. Clostridial infection following pregnancy may be fatal, and surgery is considered as the treatment of choice. We suggest a conservative management in selected cases when preservation of fertility is of major importance.Case. A 41-year-old primigravida presented with abdominal pain and fever, one day following dilatation and curettage at 20 weeks of gestation. Her abdomen was diffusely tender, with a uterus enlarged to 20 weeks' gestation. Laboratory studies were consistent with sepsis and hemolysis. CT demonstrated a gas-containing mass compressing the uterine cavity, and presence of air in pelvic veins. Blood cultures were positive forClostridium perfringens. The patient was treated conservatively, with IV antibiotics and fluid resuscitation, and recovered.Conclusion. In selected cases of infected myoma complicated by clostridial sepsis, refraining from surgical intervention is a possible therapeutic approach.

Objective We aimed to describe clinical and radiologic features of acute renal infarction (RI). Methods Clinical, computed tomography (CT), and laboratory findings were retrospectively reviewed for patients diagnosed from 1999 to 2009 with CT proof of acute RI. Possible etiology of infarction was recorded. All available published series of RI were reviewed. Results Thirty-eight patients with acute RI met inclusion criteria; 127 cases of RI from 7 previous series were pooled for analysis. The most common symptoms were abdominal pain, flank pain, nausea, and vomiting. Leukocytosis (>10 × 109/L) and elevated lactate dehydrogenase levels (>620 IU/L) were the most prominent laboratory findings. Computed tomography features included wedge-shaped hypodensities in the renal parenchyma in 35 (92%) and global renal ischemia in 3 (8%) patients; 13 patients (34%) had concomitant splenic infarction. The most common etiology was atrial fibrillation. Computed tomography determined the specific cause for RI in 5 patients (13%) and a possible etiology in 17 (45%). Exact correlation with previous series was limited by methodological diversity. Conclusion Renal infarction should be considered in the differential diagnosis of a patient presented to the emergency department with abdominal or flank pain. Laboratory workup should include lactate dehydrogenase levels. After ruling out stone disease, contrast-enhanced CT examination is essential for the diagnosis.

Persistent nephrogram, the hallmark of radiocontrast-induced kidney failure, is usually homogenous throughout the kidney and is considered as a generalized shutoff of glomerular filtration, the consequence of altered glomerular hemodynamics, affecting most glomeruli. Herein, we report an incidental finding of scattered persistent nephrogram that was noted in a septic prediabetic hypertensive patient during computerized tomography-guided drainage of a liver abscess. The peculiar patchy striated distribution pattern suggests more centrally altered renal hemodynamics, with hypoperfusion at the level of interlobar and intralobular arteries. Altered renal microcirculation in this case is likely related to the combined effects of prediabetes, sepsis and contrast medium upon renal blood flow regulation, perhaps with consequent focal hypoxic tubular damage.

This case report describes two patients with H syndrome, a multisystemic autosomal recessive disorder, caused by mutations in the SLC29A3 gene. It is characterized by cutaneous hyperpigmentation, camptodactyly or flexion contractures and other features, among them hearing loss. The two patients had hearing loss as their presenting symptom, and had mutations in SLC29A3, one of them a novel mutation. The aim of this paper is to increase awareness to this recently described disorder, and to emphasize that H syndrome should be included in the differential diagnosis of congenital or acquired syndromic hearing loss in children.

We assessed the additional value of contrast-enhanced CT versus US for evaluation of acute cervical inflammatory masses and choosing treatment strategy. We retrospectively reviewed 210 files of paediatric patients admitted with an acute inflammatory neck mass from 2005 to 2008 (M:F = 108:102, mean age 4.5 years). All patients underwent diagnostic ultrasound and Doppler of the neck; CT was performed in 25 patients within 2–72 h. Clinical and radiological findings were correlated, and imaging impact on patient management was assessed. In the 210 patients, US provided sufficient information in 184 of 185 (99.5%) patients undergoing only US. In one patient with no sonographic evidence of collection, an abscess was drained surgically on the point of fluctuation. Fluid collections were drained in 17 patients based on US findings; inflammatory processes were managed conservatively in 164. CT provided additional information in 4 of 25 patients (16.0%), revealing airways compromise in 2 and collections in 2. US provided sufficient information about the nature, location, and extent of the inflammatory mass in 97.6% of our patients, suggesting it should be the main, and generally single, imaging technique in these patients. CT should be reserved for patients with an aggravating clinical course and suspicion of deep neck infection or airways compromise.

The purpose of this study was to assess the utility of CT in characterizing pleural effusions on the basis of attenuation values and CT appearance.We retrospectively analyzed 100 pleural effusions in patients who underwent chest CT and diagnostic thoracentesis within 48 hours of each other. On the basis of Light's criteria, effusions were classified as exudates or transudates using laboratory biochemistry markers. The mean value in Hounsfield units of an effusion was determined using a region of interest on the three slices with the greatest quantity of fluid. All CT scans also were reviewed for the presence of additional pleural features such as fluid loculation, pleural thickening, and pleural nodules.Twenty-two of the 100 pleural effusions were transudates and 78 were exudates. The mean attenuation of the exudates (7.2 HU; [SD] 9.4 HU; range, 21-28 HU) was not significantly lower than the mean attenuation of the transudates (10.1 HU; 6.9 HU; range, 0.3-32 HU), (p = 0.24). None of the additional CT features accurately differentiated exudates from transudates (p0.1). Fluid loculation was found in 58% of exudates and in 36% of transudates. Pleural thickening was found in 59% of exudates and in 36% of transudates.The clinical use of CT attenuation values to characterize pleural fluid is not accurate. Although fluid loculation, pleural thickness, and pleural nodules were more commonly found in patients with exudative effusions, the presence of these features does not accurately differentiate between exudates and transudates.

Computed tomography (CT) is the ‘gold standard’ for evaluation of the cranial sutures. While prenatal cranial suture evaluation with ultrasound (US) is common, US has not been established as a postnatal screening tool. We evaluated the effectiveness of US for diagnosis of craniosynostosis (CS). During 2006, 24 infants with questionable CS were assessed with US of the sagittal, metopic, and bilateral coronal and lambdoid sutures. US findings and clinical records were reviewed retrospectively. Sixteen boys and eight girls (ages 1–11 months, mean 4.3) underwent US. The correct diagnosis was provided in 23 (95%), with equivocal findings in one patient. Cranial sutures appeared normal in 15 infants, who had normal clinical presentation at mean 5.8 months follow-up; CT confirmation was obtained in two. In eight children, US identified premature closure of one or more cranial sutures. Three-dimensional CT was performed as a preparation for surgery in four, with classical CS findings. In one case with inconclusive US findings, CT showed narrow but open sutures. Sonographic examination of cranial sutures may serve as a first imaging tool for evaluation of craniosynostosis. CT may be reserved for children with abnormal or equivocal ultrasound and for preoperative planning.

Background The association of cutaneous hyperpigmented, hypertrichotic, and indurated patches associated with hearing loss, short stature, cardiac anomalies, hepatosplenomegaly, scrotal masses, and hypogonadism has not, to our knowledge, been previously recognized as a disease entity. Objective We describe 10 patients with the above-mentioned findings. Methods Patients were clinically examined and extensive laboratory evaluation was performed. Results We describe 10 patients from 6 Arab consanguineous families with hyperpigmented, hypertrichotic, and indurated cutaneous patches involving the middle and lower parts of their bodies. In addition, patients displayed short stature, sensorineural hearing loss, cardiac anomalies, hepatosplenomegaly, and scrotal masses. Laboratory evaluation revealed growth hormone deficiency and hypergonadotropic hypogonadism with azoospermia. Cutaneous histopathologic examination showed hyperpigmentation of the basal layer with seborrheic-keratosis-like acanthosis, histiocytic infiltration, and a perivascular mononuclear infiltrate with plasma cells and mast cells throughout the dermis and subcutaneous fat. Comparison with several patients, recently reported in the medical literature, with similar cutaneous findings is made. Limitations Laboratory evaluation in some patients was incomplete because of lack of cooperation. Conclusions We suggest that our patients represent a novel multisystemic autosomal recessive inherited disorder. We call this constellation of symptoms the "H syndrome."

Respiratory infections with P. aeruginosa (PA) are a leading cause of morbidity-mortality in Cystic fibrosis (CF) patients. Several protocols for eradication are in use, however, the optimal antibiotic dosage, mode of delivery and duration of therapy has not been standardized. Still, ∼20% of the infections cannot be eradicated leading to chronic infection. Aims To analyze the rate of eradication failure of 1 st /new PA infection and to identify clinical factors associated with eradication failure. Methods 183 patients' files from 6 CF Centers in Israel and 1 in Spain were included. Demographic and clinical data for 7 years (2007–2013) were retrospectively analyzed. Results For 131 patients (72%) eradication was successful, and were divided into 2 groups: Absolute eradication – successful eradication and completed anti-PA treatment (n = 92) and Presumed eradication – successful eradication with ongoing anti-PA inhalations (n = 39). For 52 patients eradication failed: 34/52 chronically infected and 18/52 intermittent infection. Older age at CF diagnosis, older age at 1 st /new PA infection, lower FEV1%, less sputum cultures taken 1 year prior to 1 st /new isolation, previous documented PA colonization and multi/pan-resistant PA strains were all found to be associated with failure to eradication. BMI, gender, and CF-related diabetes did not influence successful eradication. No significant difference was seen in terms of HRCT Brody scores. Additionally, the different eradication protocols did not change the outcome. Conclusions Early diagnosis, increased follow-up and appropriate therapy are all required in order to enhance the rate of efficient eradication of PA in CF patients.

Ileo-colic intussusception in older children is frequently caused by a pathological lead point. Therefore, in many cases, no attempts at hydrostatic or air reduction are performed in non-pediatric hospitals. This study summarizes our experience in management of intussusception in children aged 3 years or older, in order to determine its efficacy and safety in this age group. We retrospectively reviewed medical records and radiological images of 26 cases of intussusception in 24 children older than 3 years admitted to our hospital over a 10-year period. In one child no attempt of reduction was made. Three children underwent unsuccessful imaging-guided reduction and an underlying tumor was identified at surgery and resected. In 18 cases air reduction was successful and no pathological lead point was discovered. In four children hydrostatic or air reductions failed. Manual reduction was performed, with no predisposing cause found. No complications were observed in any of our patients. Older age is not a contraindication for imaging-guided intussusception reduction attempt. Most of these patients can benefit from such an attempt, thereby avoiding surgery.

Anticonvulsant hypersensitivity syndrome (AHS) is a rare complication associated with the use of anti-epileptic medications. The syndrome's main symptoms are cutaneous eruptions, fever, hepatitis, and lymphadenopathy. We describe a 23-year-old woman who developed AHS 2 months after starting phenytoin therapy. She presented with fever, orofacial edema, skin rash, and lymphadenopathy. Four days after admission, she developed agonizing epigastric pain with diffuse epigastric tenderness. An abdominal CT scan demonstrated splenomegaly with a large, hypodense area involving the upper half of the spleen, consistent with splenic rupture. She was managed medically in an effort to avoid splenectomy. There are no other documented cases of spleen rupture linked to AHS. A possible mechanism is the alteration of lymphocytic function due to the accumulation of cytotoxic metabolites and infiltration of the spleen with lymphocytic cells, distending the capsule and predisposing it for rupture. We believe that the case presented here should increase awareness of the potentially life-threatening complications associated with AHS.

Background: In some paediatric ankle injuries, the clinical picture is suggestive of a fracture despite negative three-view radiographs. Objective: To determine the effectiveness of high-resolution US to differentiate radiographically occult fractures from sprains. Materials and methods: During a 12-month period, children aged 5–13 years who had sustained an acute ankle injury suspicious of a fracture on clinical examination, but with negative radiography, were referred for high-resolution US. Follow-up radiographs were obtained after 2–3 weeks. Results: A total of 20 children were examined. In 13, US did not reveal a fracture; small fractures were detected in 7. All patients with negative US studies had negative follow-up radiographs. In six patients with positive US the follow-up radiographs demonstrated a periosteal reaction. In one child in whom a fracture line identified by US was in the depth of the lateral malleolus, the follow-up radiograph demonstrated an area of increased bone density. Conclusions: US is effective for the detection of radiographically silent fractures of the paediatric ankle. It may be used as an adjunct to radiography in clinically suspicious, but radiographically negative ankle injuries.

Objective: t o describe the rehabilitation outcome of a case of spinal decompression sickness presenting as partial Brownsequard syndrome treated with robotic-assisted body-weight support treadmill training. Study design: Case report. Background: t ype II decompression sickness patients commonly suffer from myelopathy with gait disturbances necessitating rehabilitation. Robotic-assisted body-weight support treadmill training has been shown to improve the rehabilitation outcome of incomplete spinal cord injury. Its usefulness has not been described in decompression sickness myelopathy. Methods: Robotic-assisted body-weight support treadmill training was administrated using the Lokomat tM . primary outcomes were american spinal Cord association scale, spinal Cord Independence Measurement, Berg Balance t est, and Walking Index for spinal Cord Injury. Results: the patient was admitted 3 weeks after the diving injury, with severe paraparesis and a t11 sensory neurological level, resembling partial Brown-sequard syndrome. after 3 months of rehabilitation including 18 Lokomat sessions, american spinal Cord association score improved from C to D, spinal Cord Independence Measurement improved from 50 to 90 out of 100. Berg Balance t est improved from 35 to 43 out of 56 and Walking Index for spinal Cord Injury improved from 1 to 15 out of 20. Upon discharge he could walk with one crutch for more than 1 km. Conclusion: Robotic-assisted body-weight support treadmill training for spinal decompression sickness rehabilitation might be beneficial.

We describe a case of primary cardiac lymphoma diagnosed by transvenous biopsy under fluoroscopic and transthoracic echocardiographic guidance. A 38-year-old man was admitted because of exertional dyspnea. ECG revealed complete atrioventricular block. Transthoracic echocardiography revealed a large mass attached to the interventricular septum and protruding into the right atrium. The patient underwent a right heart catheterization and a biopsy was taken from the mass using fluoroscopic and transthoracic echocardiographic guidance. Diagnosis of malignant lymphoma was established by the biopsy specimen. The use of transthoracic echo in conjunction with fluoroscopy may be useful for the diagnosis of intracardiac mass transvenously.
