[Two cases of pancreatic serous cystadenoma].

Two cases of operated pancreatic serous cystadenoma were reported with radiological findings. A 67-year-old man was admitted to our hospital complaining of pain in the left upper quadrant. Ultrasonography revealed a mass having a mixed hypoechoic and echogenic pattern at the body of the pancreas. Computed tomography showed a honeycomb appearance. Angiogram showed hypervascularity and ERCP finding showed narrowing of the main pancreatic duct at the body of the pancreas. A 73-year-old man was detected incidentally to have a low density mass with central satellite appearance by computed tomography at the tail of the pancreas during the examination for the renal tumor. The mass showed hypervascularity and A-V shunt angiographically and narrowing of the main pancreatic duct at the tail of the pancreas by ERCP. Both patients underwent distal pancreatectomy. Histopathological findings showed microcystic pattern with single lining epithelial cells which were low cuboidal or flattened and contained intracytoplasmic glycogen.
