History of pancreatic mass now with pancreatitis. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in signal and morphology. Single punctate focus of increased T2 signal in the right lobe of the liver is likely a benign cyst.Status post cholecystectomy with associated minimal prominence of the intrahepatic and extrahepatic bile ducts. The common bile duct measures 9 mm in diameter.The splenic vein is poorly visualized and presumed thrombosed. The remaining hepatic vascular structures are patent.SPLEEN: No significant abnormality noted.PANCREAS: There is marked atrophy of the pancreas. The main duct is nondilated. There are 2 cystic foci in the distal body and tail measuring 7 mm in maximum diameter (series 901 image 24) that do not enhance. These may represent small side branch type IPMNs or residual dilated side branch ducts related to chronic pancreatitis.There is redemonstration of the soft tissue nodule in the pancreatic head which has mildly increased T1 signal and low T2 signal, but does not demonstrate enhancement or restricted diffusion. While this may represent a residual island of pancreatic tissue, an islet cell cannot be excluded.ADRENAL GLANDS: Subtle nodularity of the left adrenal gland is too small to characterize.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: Scattered normally sized retroperitoneal lymph nodes.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Postsurgical changes are noted in the anterior abdominal wall.OTHER: No significant abnormality noted.
1.Soft tissue nodule in the region of the pancreatic head as described. While this may represent a residual island of pancreatic tissue, an islet cell cannot be excluded. EUS and biopsy may be useful for further characterization.2.2, 7 mm cystic foci in the pancreas may represent residual dilated side branch ducts or side branch type IPMNs.3.No pancreatic ductal or biliary ductal abnormality.
