INTRAPANCREATIC ACCESSORY SPLEEN MIMICKING A NONSECRETING PANCREATIC NEURO ENDOCRINE TUMOR : A CASE REPORT

Abstract

The accessory spleen is a congenital anomaly caused by a failure in embryologic development of spleen tissue with occurring in 10% of general population. In 16% of these cases, this tissue is found in tail of the pancreas. Here we present a case of 55 year old female who presented to our OPD with complaints of recurrent pain abdomen. CT showed a mass in the tail of pancreas with thrombosis of superior mesenteric artery. Patient underwent spleen sparing distal pancreatectomy with celiac axis to hepatic artery bypass and mass was sent for analysis. The pathological examination showed an intrapancreatic splenic tissue. As a rare ectopic location of spleen tissue and it should be considered in the differential diagnosis of pancreatic solid tumors. IPAS should be considered as a differential diagnosis in patients with suspected incidental pancreatic neuroendocrine tumour. Preoperative diagnosis is important as unnecessary surgery can be avoided.
