Introduction: Acute appendicitis is a common surgical emergency in children, often requiring imaging for confirmation due to diverse presentations. While computed tomography scan is favored in many centers for its sensitivity, it comes with radiation exposure and higher costs. Ultrasonography, being radiation-free and cost-effective, is gaining popularity, especially in pediatric cases. However, its reported accuracy varies in the literature. This study aims to evaluate the diagnostic accuracy of ultrasonography in pediatric appendicitis cases and to determine its precision in distinguishing between simple and complicated cases of appendicitis. MATERIALS AND METHODS: A retrospective analysis was conducted on children with suspected appendicitis who presented to the department of pediatric surgery. All patients underwent ultrasonography followed by appendicectomy based on considered clinical decision. Ultrasonography findings were compared with intraoperative observations categorized as uncomplicated or complicated appendicitis. Results: Among 152 patients, ultrasonography accurately diagnosed appendicitis in 94.6% of cases, with 5.38% having nonvisualized appendices. In our group, the sensitivity and specificity of ultrasound to detect appendicitis were 94.62% and 95.65%, respectively. The diagnostic accuracy of the test is 95.63%. However, in our study, the sensitivity of the ultrasonography to correctly identify if it is a simple or complicated appendicitis was only 54.9% but had a specificity of 98.7%. Thus, ultrasonography showed a much lower sensitivity (54.9%) in distinguishing between simple and complicated appendicitis. Conclusion: Ultrasonography demonstrates high sensitivity and specificity in diagnosing pediatric appendicitis, making it a promising preoperative investigation. However, it may not accurately differentiate between simple and complicated cases. A comprehensive approach involving clinical and laboratory parameters alongside secondary imaging may be necessary for accurate diagnosis, especially in cases of perforated appendicitis.

Aim: The aim of the study was to know the clinical and radiographic outcomes of regenerative endodontic procedures of immature versus mature in young permanent incisors with apical periodontitis. Methods: Twenty non-vital, young permanent incisors with traumatic exposure between the age of 7 and 13 years were taken. Patients were divided into two groups: Group I – immature (number of teeth included = 10) and Group II – mature (number of teeth included = 10). The procedure was performed by the blood clot method as a scaffold. Biodentine (about 2–3 mm) was placed as a capping material at the cementoenamel junction. Evaluation was based on the clinical (pain, sinus, tender on percussion, swelling, mobility, intact restoration) and radiographical (Nolla stage, thickening of walls, lamina dura continuity, calcification of pulp chamber and canal, periapical healing, PAI score) parameters. Results: All 19 teeth were clinically asymptomatic after the 12-month follow-up. Radiographically, the percentage of continuous root development (in the immature group) was 100% at 12 months (P = 0.000**). Radiography revealed a reduction in the PAI scores at 12 months in the immature and mature groups. None of the treated teeth responded to the cold test after a 12-month follow-up. One patient did not come for intervention in the mature group. All the statistical tests (Chi-square, Mann–Whitney U-test, and Fisher’s exact test) were performed at a 5% significance level. Conclusion: Outcomes did not differ significantly between immature and mature groups.

Abstract Background Idiopathic CD4 lymphocytopenia (ICL) is an underdiagnosed immunodeficiency syndrome characterised by persistent low CD4 counts in the absence of HIV and other causes of lymphocytopenia. ICL patients are susceptible to opportunistic infections, with human papillomavirus, cryptococcal, and tuberculosis being the most common infections reported. Nocardiosis is rarely reported in patient with ICL. Case Presentation We herein discuss a 46-year-old female presented with complaints of weight loss, low grade fever and cough with expectoration from last four months. The patient was diagnosed with pulmonary nocardiosis and aspergillosis co-infection four years back; in addition she also had ICL. Subsequently, the patient was lost in follow-up and readmitted four years later. Bronchoalveolar lavage sample shows the presence of acid-fast bacilli in modified gram stain, which later identified as Nocardia otitidiscaviarum by metagenomic next-generation sequencing. Her CD4 counts were still found low (298 cells/mm3). After an initial improvement with trimethoprim-sulfamethoxazole (TMP-SMX), she was commenced on indefinite secondary prophylaxis. Conclusions Nocardiosis without usual risk factors should be evaluated for ICL. This case emphasize the importance of periodic follow-up with CD4 count monitoring and secondary prophylaxis therapy to prevent recurrence or the emergence of new infections in ICL. Clinical trial number Not applicable.

Background Trauma is a significant cause of morbidity and mortality worldwide among children. Nonoperative management is the standard of care in hemodynamically stable children with blunt abdominal solid organ injury. Embolization is a potential pathway, which has shown increasing evidence for benefit in adult trauma patients. However, the data in children is limited.

Congenital variants of the pancreas are being increasingly detected with the widespread use of modern imaging techniques. The underlying embryologic aberration predicts the final appearance of pancreatic development. It is essential to recognize these congenital variants, as many of these have been proven to be associated with pancreatic diseases like recurrent pancreatitis and chronic abdominal pain. Cross-sectional techniques like multidetector computed tomography and magnetic resonance cholangiopancreatography are the most used imaging techniques for the pancreas, where a radiologist comes across these variants. This pictorial aims to classify the type of variant anatomy of the pancreas, their imaging appearances, and their clinical significance.

Common variable immunodeficiency (CVID) is the most common humoral immune deficiency in adults, characterized by recurrent sinopulmonary bacterial infections. Invasive fungal infections are rarely associated with CVID. Late-onset combined immunodeficiency (LOCID) is a recently recognized variant of CVID with low CD4 counts and immunoglobulins deficiency. The current study reveals the first documented case of invasive pulmonary aspergillosis ( Aspergillus terreus ) in a patient with LOCID. A 52-year-old female with a recurrent history of sinopulmonary infections presented with acute onset fever and shortness of breath. Blood culture and bronchoalveolar lavage culture grew A. terreus . Further evaluation revealed low immunoglobulins (IgG, IgM and IgA). Moreover, she also had low CD4 counts (

The routine schedule of antenatal ultrasound scans has led to an increased frequency of detection of foetal ovarian cysts. Although most of them regress spontaneously, some may grow into large cysts and undergo torsion followed by auto-amputation. However, pre- and post-natal scans may fail to identify this event. We report a case of a prenatally diagnosed ovarian cyst that failed to resolve conservatively and was increasing in size in post-natal ultrasounds. Pre-operative ultrasound and magnetic resonance imaging failed to detect the auto-amputation. The diagnosis was confirmed on laparoscopy which offers a safe and effective method for the removal of ovarian cysts in neonates and infants.

Abstract Background and Study Design Role of 18F‐fluoro‐2‐deoxy‐2‐d‐glucose positron emission tomography‐computed tomography (FDG PET‐CT) in evaluation of renal cell cancers (RCC) and urinary bladder cancers is not standardized, and the COPPER‐T trial, which is a single centre prospective randomized study, was designed to compare it with conventional imaging for staging of clinically localized high risk RCC and urinary bladder carcinoma (Stage T2 and above). Patients and Methods There will be two subgroups of patients: RCC and urinary bladder carcinoma. In each of these, the patients will be randomized to either Arm A or Arm B. In each of the arms, each patient will be subjected to diagnostic imaging by FDG PET‐CT. The CT scan will be a contrast‐enhanced scan like that in conventional staging. A radiologist and nuclear medicine specialist will report the scan independently. The radiologist will not have access to the PET scan sequences and will only review the contrast‐enhanced computed tomography (CECT) images. In Arm A, the report of the conventional imaging modality, that is, CECT and bone scan if done, will be reviewed first by the clinician, and based on this report, a management plan will be made. Then, the PET‐CT report will be reviewed, and change in the management plan will be noted. New findings or equivocal findings if any in the PET‐CT report would be noted. In Arm B, the report of the PET‐CT report will be reviewed first by the clinicians, and a management plan will be made. Then, the CECT and/or bone scan reports will be reviewed, and any change in the management plan will be noted. Outcome and Significance Final analysis of the data after completion of the trial will help in clarifying the role of FDG PET‐CT in high risk RCC and transitional cell carcinoma (TCC) of the bladder, its diagnostic accuracy compared with conventional imaging and the impact of using it on patient management.

Renovascular hypertension (RVH) contributes close to one-fourth of the secondary etiologies of hypertension in children and a delay in diagnosis can result in adverse clinical outcomes. RVH in children is clinically silent with elevations in blood pressure measurements sometimes as its sole manifestation. Only a high index of suspicion by the clinician can prompt its detection. Despite the availability of other imaging modalities like ultrasound, computed tomography, and magnetic resonance imaging, digital subtraction angiography is still considered the gold standard to make a diagnosis of RVH. Angioplasty is considered the treatment of choice in appropriately selected patients. In this article, we shall focus on the various imaging findings, and management of RVH in children, which requires a multidisciplinary approach with a special focus on the role of interventional radiology.

Background and Purpose The ongoing coronavirus disease 2019 (COVID-19) pandemic is a multisystemic disease and involvement of the nervous system is well established. The neurological and neuroimaging features of the disease have been extensively evaluated. Our study aimed to elucidate the neuroradiological findings in COVID-19 infected patients admitted to our institute during the first and second waves of the pandemic in India. Methods This was a single-center retrospective study of all COVID-19 positive patients who underwent neuroimaging between March 2020 and May 2021. The presenting neurological complaints, the imaging findings in computed tomography (CT) imaging, and/or magnetic resonance imaging (MRI) were recorded. They recorded the findings in the subheadings of ischemic stroke, hemorrhagic stroke, parainfectious demyelination, acute encephalitis syndrome, and changes of global hypoxic changes. Patients with age-related, chronic, and incidental findings were excluded. Results The study comprised of 180 COVID-19 positive patients who underwent neuroimaging. CT scan was performed for 169 patients, MRI for 28, and a combination of both CT and MRI was performed for 17 patients. Seventy percent of patients were males, and median age was 61.5 years (interquartile range: 48.25–70.75). Out of the 180 patients, 66 patients had nonspecific findings that could not be attributed to COVID-19 infection. In the remaining 114 patients, 77 (42.7%) had ischemic findings, while 22 (12.2%) had hemorrhagic stroke. Hypoxic ischemic changes were noted in five patients. The rest of the patients had a spectrum of changes including, cerebellitis (3), tumefactive demyelination (1), COVID-19-associated encephalitis (1), hemorrhagic acute demyelinating encephalomyelitis (1), transverse myelitis (1), cytotoxic lesions of corpus callosum (1), Guillain-Barre syndrome (1), and COVID-19-associated microhemorrhages (1). Conclusion Neurological manifestations of COVID-19 infection are not uncommon, and our understanding of this topic is expanding. A complex interplay of neurotropism and direct central nervous system invasion, immune activation and cytokine storm, vasculitis, and parainfectious processes are implicated in the pathophysiology. While the most common imaging finding was ischemic stroke, followed by hemorrhagic stroke, a diverse range of parainfectious findings was also noted in our study.

Gastric outlet obstruction in neonates due to nonhypertrophic pyloric stenosis (NHPS) is a rare cause. We report the case of a 37-day-old baby boy who presented with complaints of vomiting for the last 2 weeks and an inconsolable cry over the last 2 days. He has been vomiting seven to eight times a day, a few hours after breastfeeding. On ultrasonography, the stomach was distended, while the pylorus was not hypertrophied. An upper gastrointestinal (GI) contrast study was done, which was suggestive of gastric volvulus. We performed a laparoscopy for the same. Intraoperatively, the volvulus was already resolved. We performed gastropexy. Postoperatively, he had persistent symptoms, for which an upper GI endoscopy was performed. It demonstrated a narrow pylorus, consistent with the NHPS. We performed a laparoscopic Heineke–Mikulicz pyloroplasty. The patient's symptoms had improved postoperatively. He was discharged after 5 days.

Thoracoscopic surgery was not previously accepted in the neonatal population due to inappropriate instrumentation and lack of experience. However, our experience in the last few decades has slowly yet steadily established its safety and efficacy. The major advantages that thoracoscopy offers are early recovery and fewer long-term complications. However, we are aware that this comes at the cost of a steep learning curve and the potential challenge of facing certain complications which may compel a conversion to open. There is a paucity of literature regarding intraoperative complications of neonatal thoracoscopy and its management. Conversion to open thoracotomy is appropriate, keeping patient safety in mind, and any decision made to continue management of a complication thoracoscopically is technically demanding. Iatrogenic bronchial injury is one such rare complication of thoracoscopy with a limited mention in literature. We describe below a 25-day-old patient with a bronchogenic cyst who sustained injury to the left bronchus during thoracoscopic cyst excision, which was successfully repaired thoracoscopically.

Mature cystic teratoma is a benign ovarian tumor that usually presents in reproductive-age females. This tumor usually presents with pain abdomen, bloating, and a lump. Hereby, we describe a case of an ovarian dermoid presented with features of intestinal obstruction secondary to ileo-dermoid fistula formation. A 55-year-old postmenopausal female presented with lower abdominal pain, nausea, vomiting, and the feeling of a lump in the abdomen. On evaluation and imaging, it was diagnosed as a large ovarian dermoid (with malignant transformation) with multiple fistulous communications with ileal loops. The patient was managed by laparotomy, total abdominal hysterectomy with bilateral salpingo-oophorectomy, bowel resection, and anastomosis. The patient was discharged in good condition. The rupture of malignant ovarian dermoid followed by enterodermoid fistula formation and intestinal obstruction is rare. Complete cytoreduction and bowel repair should be considered for optimal results.

Introduction Retrograde transvenous obliteration (RTO) with the assistance of a balloon (BRTO) or a vascular plug (PARTO) is an established method for treating gastric varices (GVs) secondary to portal hypertension. Most of the available studies on RTO have used lipiodol along with sclerosing agents like ethanolamine oleate or sodium tetradecyl sulfate (STS). We evaluated the safety and efficacy of RTO for treating GVs using STS as a sclerosant without lipiodol. Materials and Methods Sixteen patients (nine men, age range 16–74 years) were included in this retrospective study. Twelve patients presented with acute bleeding, two with chronic bleeding, one with large varices without bleeding, and one with refractory hepatic encephalopathy (HE). BRTO was attempted in 14 patients and PARTO in 2 patients. The technical and clinical success and complications of RTO were studied. Results The RTO procedure was technically successful in 14 (14/16, 87.5%) patients, with 13 (13/14, 93%) obtaining clinical success. One patient died due to the early recurrence of bleeding. Three patients had minor intraprocedural complications. Conclusion Retrograde gastric variceal obliteration using STS is safe and technically feasible with high technical and clinical success and low complication rate.

Context: Lung cancer is the leading cause of cancer-related deaths in the world. Computed tomography perfusion (CTP) parameters can be used to evaluate the vascular flow dynamics of lung tumours. We set out to evaluate the CTP parameters in lung cancer and correlate them with histopathological subtype and other characteristics of patients with Lung Cancer. Settings and Design: This prospective study was conducted at a tertiary care referral hospital in western India. Methods: Between January 2019 and July 2020, CTP was performed in 46 patients of lung cancer with histopathological confirmation. The CTP parameters were evaluated in detail and correlated with histopathological subtypes, staging and immunohistochemistry (IHC) markers. Analysis of variance (ANOVA) test, receiver operator characteristic (ROC) curve, Box and whiskers plot graph and Pearson correlation tests were used for statistical analysis. Results: The most common subtype was adenocarcinoma (AC) in 21 patients, followed by squamous cell carcinoma (SCC) in 15 patients and others in 10 patients. Statistically significant difference in blood flow (BF) (f = 5.563, P = 0.007), blood volume (BV) (f = 3.548, P = 0.038) and permeability/flow extraction (FE) (f = 3.617, P = 0.036) were seen in different histopathological subtypes of lung cancer. BF is the main perfusion parameter for differentiation of AC from SCC. P63 positive lesions showed statistically significant lower BF, BV and FE parameters compared to P63 negative lesions (P = 0.013, 0.016 and 0.014, respectively). Different T stages showed statistically significant differences in BF (f = 3.573, P = 0.037), BV (f = 5.145, P = 0.010) and in FE (f = 4.849, P = 0.013). Conclusion: CTP is a non-invasive imaging method to assess the vascular flow dynamics of the tumours that may predict the histopathological subtypes in lung cancer. It can be used to target large-sized lesions during biopsy and to predict the chemotherapy response.

Introduction: Posterior urethral valve (PUV) is life threatening congenital anomaly of urinary tract. Aim of the study was to correlate urethral ratio (UR) and bladder wall thickness (BWT) with cystoscopic findings in PUV patients to assess residual valves and to validate UR as a diagnostic tool for residual valves. It also aimed to assess the utility of bladder wall thickness in diagnosis of residual valves. Materials and Methods: A total of 31 patients were included in the prospective study done from 2017 to 2019. Calculation of UR was done in oblique VCUG films by dividing maximum posterior and anterior urethral diameter without the catheter insitu. Measurement of BWT was done at dome and bladder neck at full distension with feeding tube insitu and was done at same volume in follow up. The procedure was repeated at 3 months follow up. The findings were compared with cystoscopic findings for the status of residual valves as gold standard. Each patient served as control for self in the study. Results: Median age of presentation was 1 years with range of 1day to 10 years. The most common complains at the time of presentation in our study was straining (35.48%) followed by antenatally diagnosed patients (25.81%) and recurrent UTI (19.36%). Pre fulguration median UR was 2.45. Post Fulguration median UR was 1.20. It showed a statistically significant reduction (p < 0.001) after fulguration. Pre fulguration median BWT was 4 mm. Post fulguration median BWT was 2.5 mm. BWT showed a statistically significant reduction (p < 0.001) after fulguration as well. ROC curve was plotted for UR and BWT. BWT more than 1.95 mm (sensitivity-80%) and UR more than 1.2 (sensitivity-70%) indicates residual valves. Conclusion: A step ladder approach including BWT, UR and check cystoscopy can serve as a new diagnostic algorithm for the assessment of residual valves thereby avoiding extra radiation and general anesthesia exposure.

Mucormycosis is an opportunistic infection seen in immunocompromised patients or in surgical and trauma settings with Mucorales wound contamination. In immunocompetent people, disseminated mucormycosis is uncommon. To ensure survival, patients with mucormycosis require early diagnosis and aggressive treatment using a multi-modality approach. We present a case of disseminated mucormycosis in an immunocompetent patient who also had pulmonary embolism and gastrointestinal bleeding. A recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, identified retrospectively by a positive IgM against SARS-CoV-2, was the only risk factor present. This report emphasizes the increased risk of mucormycosis and thromboembolic complications following a recent SARS-CoV-2 infection, as well as its successful treatment with medical therapy alone.

Nonresponse is a major problem encountered by surveyors when conducting sampling surveys. The present study suggested a naïve modified Searls method for the elevated estimation of the population mean of the primary variable under investigation by utilizing the known auxiliary parameters. The bias along with the mean squared error (MSE) of the introduced estimator is calculated up to the approximation of the first order. We compared the presented estimator with a competing usual unbiased estimator and other competing population mean estimators regarding the issue of nonresponse. The efficiency criteria of the introduced estimator outperforming the other estimators in the competition are determined and verified using five real data sets. The MSEs for the introduced estimator and the other estimators in the competition are calculated for the five considered populations. The estimator with the least MSE or highest percentage relative efficiency (PRE) is recommended for practical exercise in different areas of applications.

Abstract Background Empyema necessitans is a rare pulmonary condition described as the presence of pus in the pleural cavity with insidious extension into the surrounding soft tissue. The common microbial aetiology of empyema necessitans is tuberculosis. Nocardiosis a cause of empyema necessitans is rarely described in the literature. We herein present a case of an 80-year-old male with empyema necessitans with osteomyelitis of rib caused by Nocardia farcinica. Case presentation An 80-year-old male presented with complaints of soft swelling on the left lower posterior chest wall associated with dry cough and breathlessness on exertion. Computed Tomography (CT) thorax demonstrated empyema necessitans with features of left fifth rib osteomyelitis. Radiological guided aspiration of the chest wall collection revealed Nocardia species and surgical drainage of abscess was performed. Matrix-assisted laser desorption/ionization time-of-flight-mass spectrometry (MALDI-TOF-MS) identified the isolate as Nocardia farcinica. He was treated with three-drug regimen: Trimethoprim-sulfamethoxazole, amikacin and ceftriaxone for 2 weeks. After showing improvement patient was discharged and advised to take oral Trimethoprim-sulfamethoxazole for the next 6 months with periodic follow-up. Conclusions As our case demonstrates, the possibility of invasive Nocardiosis should not be overlooked even in immunocompetent patients. Clinicians should aware of this rare entity while treating patients with empyema necessitans.

Herniation of brain parenchyma outside its normal enclosure (also known as encephalocele) has long been known to occur at certain classic sites and is classified accordingly. With widespread use of modern neuroimaging, the previously unknown atypical and rare sites of encephalocele have now been identified. Brain herniation into a dural venous sinus is one such recently described entity with case reports extending only upto the earlier part of this decade. With no definite clinical symptomatology, imaging is crucial to diagnose this lesion accurately and differentiate it from the more familiar entity in this region of the brain, the arachnoid granulations. Also known as occult encephalocele, focal brain herniation into dural venous sinus has few specific imaging features and characteristic sites. We report a case of a 21-year-old man with partial seizures in whom MRI of the brain revealed focal herniation of the normal temporal lobe parenchyma into the left transverse sinus and discuss the key imaging features and pathophysiology of this entity.

Maduramycosis or mycetoma is one of the chronic granulomatous diseases commonly seen in tropical regions. Microbiological cultures and biopsy are carried out for the definitive diagnosis of the disease, but they are time-consuming methods. The present study aims to correlate clinical, radiological and pathological features in eumycetoma cases to emphasize the role of 'dot in circle' sign leading to early imaging-based diagnosis. Imaging plays an important role in early diagnosis of mycetoma, which has therapeutic implications. 'Dot in circle' sign is a recently described sign in mycetoma cases on ultrasound (USG) and magnetic resonance imaging (MRI). We diagnosed four cases of eumycetoma based on clinical and imaging features, which were confirmed with histopathology. The differential diagnosis, which may mimic this sign is also discussed. The 'dot in circle' sign is seen on both ultrasound and MRI. This sign is highly specific for mycetomas. Knowledge of this sign can help in early diagnosis of mycetomas preventing misdiagnosis and further complications. (NCI-2019-0009.R1)

Direct carotid-cavernous fistula (CCF) refers to direct communication between the cavernous portion of the internal carotid artery (ICA) and the cavernous sinus due to rent in the ICA, most commonly secondary to trauma. These are generally high-flow fistula and rarely resolve spontaneously. We report a case of a young male who developed features of direct CCF after trauma, was denied any treatment for 4 years, and then presented with spontaneous thrombosis of the fistula and a residual large pseudoaneurysm of the cavernous segment of the right ICA, which was subsequently managed with parent vessel occlusion.

Cerebral proliferative angiopathy (CPA), previously known as diffuse nidus-type arteriovenous malformation (AVM) is an entity distinct from cerebral AVM, characterized by multiple small arterial feeders, large-size nidus involving entire lobe or hemisphere, and no early draining veins with normal brain parenchyma interspersed between the abnormal vessels. It is usually seen in younger age group and is more common in females. We hereby report a case of diffuse cerebral proliferative angiopathy in a 29-year-old man who presented with intracranial hemorrhage. It is important to recognize this entity to avoid aggressive treatment, thus preventing permanent damage to the normal intermingled brain tissue.

Background/Aims: The development of infection in pancreatitis increases the mortality rate up to 32%. Therefore, it is important to identify patients who are at high risk of developing infection, at an early stage. The objectives of the study were (a) to analyze the quantitative parameters of diffusion-weighted magnetic resonance imaging (DW-MRI) and apparent diffusion coefficient (ADC) in infected as well as sterile pancreatic collections (b) to establish “cut-off” values for ADC that can identify infected pancreatic collections. Materials and Methods: Prospective observational study of pancreatitis cases who underwent DW-MRI from August 2018 to July 2019 were enrolled in the study. The collections were analyzed for diffusion restriction. The average of the three ADC values from the wall and center of collection was noted. Results: Infected collections were seen in 7 and sterile collections observed in 11 cases. The optimal cut-off ADC value to differentiate sterile and infected collection in our study was 1.651 × 10-3 mm2/s (sensitivity of 81.8%; specificity of 100.0%). ROC curve for mean ADC from the wall showed a significant diagnostic accuracy with AUC: 0.91; 95% CI: 0.77-1.0 (P = 0.004). Conclusion: DW-MRI is a reliable noninvasive technique to differentiate sterile and infected pancreatic collections. ADC values from the periphery of the collection can predict infected pancreatic collections at an early stage. DW-MRI should not be considered as a substitute for aspiration cytology in patients with septic symptoms and absent diffusion restriction on MRI.

Basidiobolomycosis is an infection due to the fungus Basidiobolus ranarum, an environmental saprophyte found worldwide. We are reporting youngest case of Gastrointestinal Basidiobolomycosis (GIB) in a two month old boy from India. He presented with a mass in right iliac fossa with the signs of intestinal obstruction. Histopathology of the lesion showed broad aseptate hyphae. It disseminated to kidneys. Aspirate culture from nephrostomy yielded growth of B. ranarum. It is important to differentiate it from mucormycosis to institute right therapy. Culture remains the gold standard for its diagnosis. Keywords: Disseminated gastrointestinal basidiobolomycosis, Entomophthoramycosis, GIB

Caroticocavernous fistulas (CCFs) occur due to an abnormal communication between the high-pressure carotid artery system and the relatively lower pressure cavernous sinus system. They present with dramatic clinical presentations comprising among other things a swollen red eye with associated loss of vision to a varying degree. Blunt trauma sustained to the head, especially by two-wheeler riders, is the most common cause of the direct CCF and hence a practicing interventional radiologist in a developing country is very likely to encounter this entity in clinical practice. The authors intend to present a pictorial essay of the clinical presentations, imaging findings, endovascular management, and clinical follow-up for CCFs.

Eumycetoma in the maxillofacial region is a rare entity and long-term disease-causing osteomyelitis may possess a diagnostic challenge. We present a case of a 27-year female with painless swelling on the right cheek and right lower third of the face for 10 years. Orthopantomography (OPG) showed an extensive ill-defined radiopaque lesion (ground glass appearance). Histopathological examination revealed chronic granulomatous osteomyelitis with focal suppuration and reddish-brown grains of organisms, morphologically resembling mycetoma. Given consistent negativity for Gram's stain and positive GMS and PAS stain, diagnosis of Eumycetoma was favored over Actinomycetoma. To the best of our knowledge, this was the first case of extensive chronic granulomatous osteomyelitis caused by eumycetoma species.

Primary renal chondrosarcomas are rare tumors that are high-grade in nature and, unfortunately, have poorly understood pathogenesis and extremely low prognosis. The coexistence of a discrete malignancy in the urinary bladder is even rarer, with the occurrence of distinct papillary urothelial carcinoma in the urinary bladder in this case. The clinical presentation is nonspecific, and the primary radiological investigations have a limited scope in providing specific diagnosis of this entity. The final diagnosis is possible on thorough histopathological examination of the resected specimen, which requires extensive sampling and meticulous reporting. As of now, the only way to achieve a better prognosis is by early diagnosis. It is necessary to keep the possibility of occurrence of sarcomas at rare sites in the differential diagnoses. The cytogenetic and molecular abnormalities associated with this entity need to be elucidated to achieve a more satisfactory outcome concerning the overall management of the patient.

Bladder rhabdomyosarcoma (RMS) in children, at presentation are often large, situated in close proximity to vital structures. This makes the surgical resection challenging. Hence, chemoradiotherapy is often used first. For those tumors which are amenable for resection, laparoscopy can serve as a better alternative. A 5-year-old boy presented with lump in the abdomen. MRI revealed a solid tumor of size 4.8 × 4.3 × 5.3 cms arising from dome of bladder. Tru-cut biopsy of the tumor showed features of RMS, after which VAC (Vincristine, Actinomycin-D, Cyclophosphamide) chemotherapy was started. By the end of two cycles of chemotherapy, patient required hospital admission multiple times due to chemotherapy toxicity. Review imaging of the tumor showed >60% reduction in size. Laparoscopic bladder preserving partial cystectomy was done. Post-operatively patient was discharged after six days. During follow-up, patient had no urinary symptoms. The resected specimen had tumor cells at inferior margin. Adjuvant chemotherapy course was completed. Two years after the surgery, patient remains free of recurrence. Laparoscopy serves as a good alternative to open surgery for bladder RMS surgeries. Laparoscopic bladder preserving surgery can be done with good access, limiting the operative morbidity. Patients can benefit from smaller scars and speedy post-operative recovery.

Background: Hypoparathyroidism is a condition characterized by hypocalcemia and hyperphosphatemia due to insufficient secretion of parathyroid hormone (PTH). The common causes of hypoparathyroidism are postsurgical and autoimmune. We describe a case of hypoparathyroidism precipitated by mumps. Clinical Description: A 17-year-old boy was brought to us with altered sensorium following 2 episodes of generalized tonic-clonic seizures within the last 4 h. He required mechanical ventilation, but severe laryngospasm made intubation difficult. He had been suffering from a febrile illness that appeared to be mumps for the preceding 4 days. The only salient biochemical abnormality was hypocalcemia and hyperphosphatemia. Neuroimaging and cerebrospinal fluid examination were normal. Hypoparathyroidism was suspected and confirmed by low PTH levels. He also developed secondary hypothyroidism. Management and Outcome: The child had no symptoms of hypocalcemia in the past. He was started on intravenous calcium and calcitriol. He showed dramatic improvement in sensorium with normalization of serum calcium levels. He was extubated after a week. At discharge, there were no neurological sequelae and the sick euthyroid syndrome had resolved. Viral serology for mumps was reactive by the 3rd week of illness. Conclusion: Although viral infections have been described as triggers for other endocrinopathies, we could not find any association with hypoparathyroidism. An exhaustive literature search we could not find any similar case reports of hypoparathyroidism during or following mumps. Whether mumps infection had any role in the pathogenesis of the hypoparathyroidism or only unmasked an underlying endocrinopathy remains uncertain.

Choledochal cysts (CDC) are rare biliary tract anomalies characterized by congenital dilatation of the extrahepatic and/or intrahepatic bile ducts. CDC excision with hepatico-enterostomy is the preferred surgery in modern era. Perioperative blood loss in a case of laparoscopic choledochal cyst excision (LCCE) is usually minimal and managed by conservative treatment such as blood transfusion and correction of coagulation factors. Massive hemorrhage in LCCE is rare and reported intraoperatively or within the first 3 postoperative days. Hereby, we present an unusual case of arterio-duodenal fistula, post LCCE presenting as delayed massive upper gastrointestinal bleeding in a male child and its successful endovascular management.

Mucinous Tubular and Spindle Cell Carcinoma (MTSCC) is infrequently seen renal malignancy with favorable outcome, when diagnosed in the early stage. Once out of kidney it is have lethal course. Radiologically MTSCC is heterogeneously hypo-enhancing renal mass in delayed phase, may mimic to papillary renal cell carcinoma and in histopathology showed these tumoral cells shows complex immunophenotype expression. As this does not show enhancement pattern of common renal cell carcinomas, radiological diagnosis may be challenging. Histopathological reporting is also tedious indeed necessary to reach definitive diagnosis, which help in tailoring follow up and prognosis. Metastatic disease has dismal outcome and responds poorly with adjuvant therapy and patient succumbs within short span of time.

Arteriovenous fistula (AVF) is direct abnormal communication with the shunting of blood from an artery to a vein without intervening capillary network. AVF in preauricular location is uncommon, and most of the cases are posttraumatic or iatrogenic. The endovascular route is the preferred approach for treating such a lesion with better cosmetic outcome, however surgical excision may be required for complex cases.

The sacrococcygeal region is the most common site for the extragonadal germ cell tumors comprising seminomatous and non-seminomatous tumors. Seminomatous tumors are seminomas, and non-seminomatous tumors comprise mainly teratoma (mature and immature), yolk sac tumor (YST), embryonal carcinoma (EC), and choriocarcinoma. These tumors occur in newborns, infants, and adolescents. Other common sites for extragonadal germ cell tumors are the brain and mediastinum, although they may occur anywhere in the body. These tumors may occur in mixed as well as pure form. So, sectioning from different areas should be done before labeling them as pure germ cell tumors. YST, in its pure form, is rare and therefore should not be missed as it is chemosensitive. The patient should be thoroughly assessed clinically. Imaging also becomes necessary while evaluating swelling in the sacrococcygeal region and can aid in differentials. When the clinical and imaging suspicion of either Sacrococcygeal teratoma or other germ cell tumor is high, serum biomarkers as alfa-fetoprotein should be requested. The serum levels are necessary and should be done preoperatively, postoperatively, and during the course of chemotherapy as follow-up. However, the final diagnosis rests on the histopathological diagnosis. We report one such case of pure YST in the sacrococcygeal region in a 9-month-old female child. The imaging suggested sacrococcygeal teratoma type 4, and high alfa-fetoprotein levels were determined postoperatively.

Behçet’s disease is a systemic vasculitis with a wide spectrum of manifestations. Although pulmonary involvement is typical, the presence of pulmonary arterial aneurysms is associated with a high incidence of mortality and morbidity. We report two cases of Behçet’s disease with pulmonary arterial involvement who presented with hemoptysis, showed significant treatment response, thus, highlighting the importance of early diagnosis and therapeutic management.

Pleural effusion is easily diagnosed often managed optimally with standard protocols. It at times, is a diagnostic dilemma as it comes with big list of differential diagnosis. Pleural effusion due to pancreaticopleural fistula (PPF) is a rare and on right side is even rarer. Detailed history along with high index of suspicion in required to diagnose PPF, which is confirmed by increased level of pleural fluid amylase and lipase along with magnetic resonance cholangiopancreatography (MRCP) or endoscopic retrograde cholangiopancreatography (ERCP) demonstrating fistula tract. Here we report the case of a young patient who presented with respiratory distress and was wrongly diagnosed as right sided tubercular effusion which later turned out to be pancreatic effusion. Management in our case was multi-disciplinary involving pulmonologist, gastroenterologist, radiologist and thoracic surgeon.

Herlyn-Werner-Wunderlich syndrome (HWW) is a triad of didelphys uterus, obstructed hemivagina, and ipsilateral renal agenesis. It is a combined anomaly of Mullerian and mesonephric ducts. It usually presents in adolescent females after menarche with nonspecific symptoms of pelvic pain, dysmenorrhea, and rarely a palpable pelvic mass. We report here, a case of an 18-year-old female presenting with complaints of lower abdominal pain and dysmenorrhea where magnetic resonance imaging (MRI) confirmed the diagnosis of HWW syndrome. MRI is the imaging modality of choice for diagnosis of HWW syndrome and associated complications such as endometriosis.

Gall bladder carcinoma is an aggressive malignancy with varied presentation. Liver is most commonly involved initially with distant metastasis in virtually all possible organs. We report a case of middle aged female who presented with pain in upper abdomen and progressive jaundice. Imaging studies were suggestive of gall bladder carcinoma involving hilum with disseminated osteosclerotic lesions and metastasis to Urinary Bladder (UB). Patients of carcinoma gall bladder with disseminated metastatic disease have poor prognosis and are managed with palliative chemotherapy. To the best of our knowledge, this is one of the rare initial presentation of gall bladder carcinoma in the literature.

Choledochal cyst (CC) is an important surgical cause of jaundice in infants. Infantile variant of CC can mimic biliary atresia in clinical presentation. CC associated with biliary atresia is well described in literature. We encountered an atretic variant of CC that has not been described in literature ever. The characteristics of this unusual case, management, and proposed hypothesis to its pathogenesis are discussed here.

Context: The emergence of drug resistance to trimethoprimsulfamethoxazole, the penicillins, cephalosporins, and fluoroquinolones by Uropathogenic Escherichia coli (UPEC) has limited the options for selecting the appropriate antibiotic for the treatment of urinary tract infections. Aims: The The E. coli isolates, which were obtained from the culture of urine samples,were studied for their antibiotic resistance patterns, with special reference to the antimicrobial activity of the fluoroquinolones and the production of the extended spectrum ß-lactamases. (ESBL), Settings and Design: This was a hospital based, prospective study which was done for a period of eighteen months. Material and Methods: This study was done by using the standard culture techniques for urine samples, the modified Kirby-Bauer disk diffusion method for the antibiotic susceptibility testing and the disk diffusion method to confirm the ESBL production by the clinical isolates of E. coli in urine. The sensitivity pattern was correlated with the clinical condition and the presence of the risk factors. The statistical analysis which was used: The statistical analysis was done by using the proportions of sensitive, resistant and intermediates. Descriptive statistics like the total, mean and percentage were done by using the Statistical Package for the Social Sciences (SPSS), version 15.0. Results: The hospital isolates showed high degrees of resistance to the penicillins, cephalosporins, nalidixic acid and the fluoroquinolones, with 59% of the isolates being ESBL producers. Conclusions: The incidence of the multidrug resistant strains of Escherichia coli has been steadily increasing over the past few years. The knowledge on the resistance pattern of the bacterial strains in a geographical area will help in guiding the appropriate and the judicious use of antibiotics. Also, the formulation of an appropriate hospital antibiotic policy will go a long way in controlling these infections.
