Reason: pancreatic mass seen on abd US History: pancreatitis, wt loss, anorexia ABDOMEN:LIVER, BILIARY TRACT: Gallbladder sludge. No suspicious hepatic lesions.SPLEEN: No significant abnormality noted.PANCREAS: 1.1 cm T2 hyperintense nonenhancing lesion at the pancreatic head just proximal to the ampulla. A branch off the main pancreatic duct appears to communicate with this lesion, and this likely represents a side branch IPMN without evidence of suspicious features. This is best seen on delayed postcontrast imaging. A couple other smaller similar-appearing lesions are also seen. Mild diffuse prominence of the duct measuring up to 3 mm with a beaded appearance. Pancreatic head fullness with no distinct enhancing or hypoenhancing lesion except for what is described immediately above. Infiltrative T2 signal seen throughout the head of the pancreas could be edema related to a component of focal acute pancreatitis on chronic pancreatitis.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Focal acute on chronic pancreatitis as above. 1.1 cm and smaller nonenhancing lesions in the pancreatic head with apparent communication with the ducts likely represent small side branch IPMN's. Follow-up until resolution is recommended to exclude underlying pancreatic head lesion.
