Obstructive Jaundice as a Complication of Macrocystic Serous Cystadenoma of the Pancreas

Abstract

Macrocystic serous cystadenoma is an unusual and essentially benign pancreatic tumor. Herein, we report on a 40-year-old woman diagnosed with macrocystic serous cystadenoma who presented with obstructive jaundice. A cystic lesion in the head and body of the pancreas was revealed by abdominal computed tomography. Intraoperative pancreatic cyst aspiration ruled out mucinous cystic neoplasm which has a malignant potential. The pancreatic cyst fluid cytology was basophilic amorph materials concluded as benign cystic lesion. Internal drainage was performed instead of pancreatic resection which showed good outcome. Biliary obstruction is a rare complication of serous cystadenoma. This case describes an unusual clinical presentation of macrocystic serous cystadenoma.
