Case of a Cat with an Asymtomatic Non-Neoplastic True Pancreatic Cyst

Abstract

A mass was found incidentally in the peritoneal cavity of a 10-year-old contraceptive cat on radiographic examination as part of a wellness check. A computed tomography scan revealed a cystic mass in the left lobe of the pancreas. A sample of cystic fluid taken intraoperatively contained pancreatic enzymes and epithelial cells. Resection of the pancreatic cyst required partial excision of the left lobe of the pancreas. The histopathologic diagnosis was non-neoplastic true cyst. The cyst was difficult to detect because of its asymptomatic nature. Computed tomography and examination of cystic fluid were useful for demonstrating the presence of this pancreatic cyst. In view of the risk of cystic fluid leaking into the peritoneal cavity, surgery should always be considered for a pancreatic cyst, regardless of whether it is benign or malignant, particularly if it is not reducing in size.
