Case Discussion

The pancreatic serous cystadenoma is an epithelial neoplasm that mostly affects women with a slight predominance in the pancreatic head. The most common presentation is with numerous small cysts that give a "honeycomb" appearance (microcystic variant), thin septa, and sometimes with a central scar. In some cases the cysts may increase in size of 2 cm or be made up of one or a few voluminous cysts (oligocystic or macrocystic variants) which will likely lead to a differential diagnosis including mucinous neoplasms. The serous cystadenoma is always benign
