Hypertrophic pyloric stenosis (HPS) is a frequent cause of vomiting in young infants, with an incidence of 1.5 – 4 per 1000 live births, depending on demographic group. The gold standard diagnostic test is abdominal ultrasound targeting the pylorus, and the measurement thresholds for determining an abnormal pylorus are well established. The objective of this study was to assess whether visual, subjective assessment of the pylorus was as accurate in diagnosing HPS as traditional formal measurements. Read More

Pancreatic tumors are very rare in the pediatric population, with a reported incidence of 1.8 cases per 1,000,000 children in the United States. Several case reviews in the literature from large referral centers have yielded relatively few cases of pancreatic neoplasm. The most commonly reported pancreatic tumors include solid pseudopapillary epithelial neoplasm (SPEN), pancreatoblastoma, and neuroendocrine tumors. Other, more commonly encountered pancreatic abnormalities include trauma and pancreatitis. Given their rarity, the imaging characteristics of pancreatic lesions at MRI may be unfamiliar. The purpose of this exhibit is to present the typical imaging appearance of various pancreatic lesions in children. Read More

5 yo male with PMHx significant only for autism presented to ED with acute abdominal pain, hematemesis, and melena. Patient was tachycardic but normotensive with Hgb 5.6 g/dL (normal 11.5 – 13.5 g/dL) requiring transfusion. Patient was also jaundiced with scleral icterus, markedly elevated liver enzymes, and direct hyperbilirubinemia. Abdominal X-ray and Abdominal US did not demonstrate significant bowel pathology. However, gallbladder was abnormal with thickened, hyperemic wall and abundant internal debris. Common bile duct was massively dilated to the level of ampulla and filled with heterogeneous, avascular debris. No cholelithiasis or mass was demonstrated. Based on US, a differential diagnosis of cholecystitis, cholangitis, or choledochal cyst complicated by hemobilia was offered. MRI demonstrated dilated central intrahepatic and extrahepatic bile ducts containing layering T1 bright, T2 dark material. On arterial post-contrast images, the right hepatic artery was immediately adjacent to dilated common hepatic duct and blush of enhancement was seen concerning for active hemorrhage into type 4b choledochal cyst. The patient proceeded to diagnostic angiography, which was unable to demonstrate a site of arterial bleeding. Biliary drain was placed across the choledochal cyst with initial drainage of bloody material followed by drainage of bile. Patient subsequently underwent open cholecystectomy. Pathology demonstrated "mucinous papillary proliferation with increased histiocytes in lamina propria, consistent with gallbladder changes in Metachromatic Leukodystrophy (MDL)." Subsequent brain MRI demonstrated classic findings of MDL. Read More

Focal nodular hyperplasia (FNH) is a benign lesion. Gadoxetate disodium (Eovist), a hepatocyte specific contrast agent, is becoming more widely used in pediatric MR imaging. FNH is composed of hepatocytes and should demonstrate homogeneous enhancement on the hepatobiliary phase of imaging; however, in clinical practice a variety of enhancement patterns have been observed. The purpose of this study is to document the features of FNH on hepatobiliary phase MRI in pediatric patients. Read More
