Intra pancreatic accessory spleen mimicking pancreatic insulinoma: a case report

Accessory spleens are a congenital anomaly caused by abnormal fusion during embryonic development, leading to the presence of splenic tissue in unusual locations, such as the tail of the pancreas. Their pronounced arterial enhancement can cause them to be mistaken for a neuroendocrine tumor, particularly an insulinoma. We report the case of a 61-year-old patient with recurrent hypoglycemia who was referred for suspected neuroendocrine tumor.
