Although the second most common site of the accessory spleen is the tail of the pancreas, intrapancreatic accessory spleens (IPAS) are rarely recognized radiologically. When an accessory spleen is located in the pancreas, it may mimic a hypervascular pancreatic tumor. We report a case of intrapancreatic accessory spleen which radiologically (on TC) mimicked a neuroendocrine pancreatic tumor (PNET). It was not possible to be sure that the pancreatic nodule had no malignant potential; because of the close proximity to splenic vessel we performed en bloc resection of the spleen and distal pancreas. Postoperative course was uneventful. IPAS must be considered in the differential diagnosis of pancreatic tail tumors, particulary an asymptomatic small PNET; new and adequate diagnostic studies have demonstrated utility in defining these lesions. We review pertinent literature.
