A 57-year-old woman was found to have splenic tumors by ultrasonography at a physical checkup, and was admitted to our hospital. She had no subjective symptoms and there were no particular problems in her medical history. Laboratory data on admission were normal. Abdominal ultrasonography and computed tomography showed numerous hypoechoic and low density solid masses in the spleen. In contrast and dynamic studies, they were enhanced. The magnetic resonance image showed isointensity masses on Tl-weighted images and slightly high intensity masses on T2-weighted images. In a Gd-DTPA study, they were found in slightly high intensity areas. Splenic angiograms showed numerous hypervascular tumors and a splenic aneurysm. The splenic artery was winding and dilated. The splenic aneurysm was resected in addition to splenectomy. The cut surface of the resected spleen showed numerous well-circumscribed, but unencapsulated white tumors. The histological diagnosis of the splenic tumors was hamartoma cosisting of red pulp components. The same histological findings were also detected in accessory spleen.
