Abstract:

Accessory spleen has been reported to occur in about 10-30% of the population and has been identified in a variety of areas such as the tail of the pancreas, the pelvis and the scrotum; however, the splenic hilum is the most common site. As imaging modalities improve, accessory spleens are frequently detected as an incidental finding on computed tomography (CT) and magnetic resonance imaging (MRI) which may mimic a neoplasm. We report a case of intrapancreatic accessory spleen simulating a neuroendocrine neoplasm and a case of accessory spleen presenting as a submucosal mass suggestive of a gastrointestinal stromal tumor. Finally, we discuss the common differential diagnosis, radiologic features, and possible management of accessory spleens.
