An Intrapancreatic accessory spleen presenting as a neuroendocrine tumor.

Abstract:

: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. KEY WORD: Intrapancreatic accessory spleen, Pancreatic neuroendocrine tumor. :Sebbene il secondo sito più comune della milza accessoria sia la coda del pancreas, la milza accessoria intrapancreatica è raramente riconosciuta radiologicamente. Quando una milza accessoria si trova nel pancreas, può simulare un tumore pancreatico ipervascolare; riportiamo un caso che alla TC era diagnosticato come un tumore pancreatico neuroendocrino. Non potendo escludere la potenzialità maligna del nodulo pancreatico, è stata eseguita una spleno-pancreasectomia distale. Il decorso postoperatorio è stato regolare. La milza accessoria intrapancreatica deve essere considerata nella diagnosi differenziale dei tumori della coda del pancreas, in particolare un piccolo tumore neuroendocrino asintomatico; nuovi e adeguati mezzi diagnostici hanno dimostrato utilità nel definire queste lesioni; esaminiamo la letteratura pertinente.
