Diagnostic Ultrasound - Abdomen and Pelvis
Pancreatic Duct Dilatation Chronic Pancreatitis Chronic Pancreatitis (Left) Transverse transabdominal ultrasound shows a dilated pancreatic duct ſt communicating with a small pseudocyst st in the body of the pancreas. (Right) Axial T2 HASTE MR better demonstrates mild pancreatic ductal dilatation ſt communicating with the small pseudocyst st. Note tiny dilated side branches in the tail of the pancreas. Pancreatic duct strictures were also seen (not shown) in this patient with a history of pancreatitis. Differential Diagnoses: Pancreas Pancreatic Ductal Carcinoma Pancreatic Ductal Carcinoma (Left) Transverse oblique transabdominal ultrasound shows pancreatic ductal dilation in the body of the pancreas ſt. (Right) Coronal CECT was performed in the same patient to further characterize the cause of the pancreatic ductal dilatation. The dilated duct terminates abruptly ſt at the site of a large, ill-defined mass in the pancreatic head . Intraductal Papillary Mucinous Neoplasm (IPMN) Intraductal Papillary Mucinous Neoplasm (IPMN) (Left) Transverse transabdominal ultrasound shows marked pancreatic ductal dilatation ſt with lowlevel internal echoes and an ill-defined hypoechoic mass posteriorly st. (Right) Axial CECT demonstrates marked pancreatic ductal dilatation ſt with an infiltrative soft tissue mass posteriorly , encasing the celiac axis. Note cavernous transformation of the portal vein st due to venous occlusion from the mass which was proven by biopsy to be malignant transformation of a main duct type IPMN. 929
