A Case of Intrasplenically Grown Non-functioning Pancreatic Endocrine Tumor

Abstract

A 62 year-old male was admitted to our hospital for detailed examinations of a low density mass in the spleen by abdominal CT scan at a physical checkup. Abdominal CT scan also demonstrated portal obstruction and collateral veins around pancreatic head. Furthermore, abdominal angiograhy showed a hypovascular lesion in the spleen. Upper gastroendoscopy demonstrated esophageal varices, which were eradicated after EVL. The above examinations, however, could not make the definitive diagnosis, therefore splenectomy was carried out on 5 July 2000.
The tumor size of the cut surface was 4×5cm in diameter. Histopathological diagnosis was non-functioning pancreatic endocrine tumor. The patient remains well with no evidence of recurrence one year and seven months after the operation.
