There is a well-defined multilobulated cystic mass of the pancreatic head measuring (60 x 55 x 45 mm), composed of numerous cysts of variable sizes, separated by enhanced septa with central calcification. This pancreatic mass is in contact with the superior mesenteric vein, portal vein, IVC, and left renal vein with no vascular invasion. The common bile duct is displaced anteriorly, but not dilated. Mild dilatation of the pancreatic duct is noted. No enlarged lymph nodes are noted.
- hiatal hernia
- small diverticulum of the 2nd part of the duodenum
- small simple hepatic cyst
- small umbilical hernia of epiploic content
- gallbladder (history of cholecystectomy 20 years ago)
- colonic diverticulosis
- endometrial thickening (patient referral to a gynecologist)
The clinical history and the CT features suggest probably a serous cystadenoma of the pancreas. As compared to the previous CT (not shown) done 3 years ago the pancreatic mass was relatively stable.
