Radiological diagnosis of rare pancreatic serous cystadenoma

Serous cystadenoma of the pancreas, also known as microcystic adenoma, is a very rare type of pancreatic neoplasm. It is a benign cystic lesion. It is composed of many small cysts lined by cuboidal or flattened cells containing glycogen. Herein, we report a rare case of serous cystadenoma of the pancreas in an 82-year-old male. The tumor was located in the body and tail of the pancreas and postoperative sample revealed a sponge-like appearance due to multiple tiny cysts containing clear serous fluid. Microscopic analysis showed cystic spaces lined by cuboidal cells with intracytoplasmic glycogen.
