Serous cystadenoma of the pancreas


A female in her 70s is the typical patient for this benign lesion. In this case, the serous cystic adenoma is of the microcystic variant. Even on CT, some small cysts can be appreciated. The tumor can look like a branch-duct IPMN, however unlike IPMNs it has no communication with the ductal system. 

Serous cystic tumor is the only pancreatic cystic tumor that is not premalignant.

Incidental adenomyomatosis of gallbladder is shown.
