    Abstract Rosai Dorfman disease is a rare but benign and self-limiting disorder. A case of Rosai Dorfman disease in a 16-year-old female with classic radiological and pathological findings is presented. T2W hypointense signal of the soft tissue masses was a distinguishing MRI feature. Contribution: Rosai Dorfman disease is often overlooked in the differentials of lymphadenopathy and soft tissue masses on account of its rarity. This case report comprehensively discusses the imaging approach to this rare disorder.

    Abstract Isosexual precocious puberty with ovarian masses in long-standing juvenile hypothyroidism is well described in the literature as Van Wyk Grumbach syndrome (VWGS). The present case reports this rare entity in a 4-year-old girl who was referred for imaging to evaluate the cause of non-traumatic bleeding per vagina. Antecedent history, clinical features and thyroid function tests were consistent with long-standing juvenile hypothyroidism with documented clinical response to thyroxine replacement therapy. Contribution: Typical clinical and radiological features of the syndrome are reported, which helps in the early diagnosis and management, henceforth avoiding the associated complications.

    Abstract Abstract Midgut malrotation is usually present in the early neonatal period with intestinal obstruction and bilious vomiting. However, sometimes it may present later in childhood and adolescence with atypical features and then may remain undiagnosed for long, adversely affecting the growth and development of the child. Here we describe three cases of intestinal malrotation with various atypical presentation and imaging findings.

    Abstract Abstract Background Chronic kidney disease (CKD) is a significant health issue in pediatric patients due to fibrosis progression. Shear wave elastography (SWE) is a noninvasive technique used to assess fibrosis in CKD, but its efficacy needs to be better established. This study aimed to compare SWE with nuclear scan in assessing fibrosis in pediatric CKD patients. Aim To determine the area of scarring/fibrosis of each kidney using shear wave elastography in chronic kidney disease and compare it with technetium-99m dimercaptosuccinic acid (DMSA) results. Methods A prospective study included 39 chronic kidney disease patients who underwent shear wave elastography and grayscale ultrasound. DMSA scans were performed to identify scar areas of the kidneys. Young modulus was recorded for each pole of both kidneys and compared with scar areas on DMSA. Thirty-nine age-matched controls underwent shear wave elastography to estimate the average elasticity value in the normal population. Results Thirty-nine CKD patients underwent this study, with 10 females and 29 males. The median age was 6.5 years. The cutoff value of cortical thickness ≤ 10.2 predicted scar on DMSA with a sensitivity of 79% and a specificity of 77%. The cutoff value of elasticity value ≥ 5.57 kPa predicted scar on DMSA with a sensitivity of 87% and a specificity of 96%. Median SWE values were significantly higher with the scar on DMSA (12.6 kPa) compared to no scar on DMSA (4.1 kPa). The controls mean values and standard deviation were 2.42 kPa and 0.45 kPa, respectively. Conclusions Shear wave elastography has revealed that patients with chronic kidney disease exhibit higher values in the areas where scarring has occurred, compared to non-scarred areas. Fortunately, integrating shear wave elastography into routine ultrasonography assessments is a straightforward and painless process that requires no additional preparation from the patient. Not only is this method time efficient, but it also eliminates the need for potentially risky radiation exposure ...

    Abstract Biliary atresia (BA) is a progressive destructive cholangiopathy of unknown etiology that presents in early infancy. It has a worldwide frequency of 1:8,000–1:15,000 and is common in Asia than in the west. Based on the level at which the lumen of the extrahepatic duct is obliterated, BA is classified into three types. Type III is the commonest (∼85%) type and has the most proximal level of obstruction in the porta hepatis, while type II in which the atresia is at the level of the common hepatic duct, is the least common (∼2.5%) and has been rarely reported. Here, we report the imaging features of an infant with type IIB biliary atresia.

    Abstract Introduction: Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) infection, also known as Coronavirus Disease-2019 (COVID-19) is the global pandemic, first described in Wuhan city of China in December 2019. Its diagnosis depends upon real time Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR). On chest Computerised Tomography (CT), it is almost similar to other viral pneumonia with extensive parenchymal involvement. Semiquantitative scores depicting this extensiveness of involvement could correlate with disease severity, laboratory parameters, mortality like Intensive Care Unit (ICU) admission, requirements of ventilatory support and longer hospital stay. Aim: To define the role of chest CT score in determining disease severity, predicting poor prognosis and mortality of COVID-19 pneumonia in short-term follow-up. Materials and Methods: This prospective study enrolled 547 admitted real time RT-PCR positive patients for COVID-19 at All India Institute of Medical Sciences, Rishikesh, India from 15th April 2021 to 31st May 2021. All patients were assigned semi-quantitative CT scores based on the extent of lung parenchymal involvement of 20 lung regions in chest CT. Finally, 205 patients were enrolled for the final analysis. Clinical severity was matched with chest CT scoring and laboratory findings. Survival curves along with univariate and multivariate analysis was applied to define the role of CT scoring in predicting short-term prognosis. Results: Total 205 subjects were included in the study, of which the chest CT score showed a significant association with clinical severities (p-value <0.001). CT score was correlating significantly with increased serum C-Reactive Protein (CRP) (p-value=0.001) and D-dimer (p-value=0.01), and decreased lymphocyte count (p-value <0.001). A CT score ≥31 was found to be associated with an increased risk of mortality in both univariate and multivariate analysis {Odd Ratio (OR)=276.8; 95% Confidence Interval (CI)=45.21-1695.43; p-value <0.001}.

    Abstract Hepatic complications of malposition of umbilical venous catheter (UVC) are uncommon and occur due to extravasation of hypertonic fluids and the blood products in the liver tissue. Various hepatic complications include thrombosis of hepatic vessels, hepatic necrosis, hepatic fluid collections, and hematoma, with the intraparenchymal liver lesions seen along the course of ductus venosus. Radiologists must be aware of these complications and their imaging findings, as the timely recognition and immediate management can prevent the fatal outcome. Here, we present a rare case of intraparenchymal liver lesions associated with malposition of UVC in a preterm baby.

    Abstract Paragangliomas are the neuroendocrine tumors which arise from the chromaffin cell. Tumors arising from the adrenal medulla are known as pheochromocytomas, while others originating from the extra-adrenal site are known as extra-adrenal paragangliomas. Paraganglioma can be multifocal which can arise synchronously or metachronously. Paragangliomas are less functionally active than the pheochromocytomas; they secrete noradrenaline and rarely dopamine, while adrenal pheochromocytomas secrete adrenaline or nor-adrenaline. Nonfunctional multifocal paragangliomas are very rare. We report a case of a 45-year-old female with multifocal nonfunctional paragangliomas of the retroperitoneum and urinarybladder which were surgically removed, and the diagnosis was confirmed on histopathology.
