Abstract:
A 46-year-old man presented with a huge splenic artery dissecting aneurysm that had been incidentally found and was successfully resected before rupture. The histopathologic findings were compatible with segmental mediolytic arteriopathy (SMA). Simultaneous involvement of the left renal and right common iliac artery was observed. The patient was also found to have an adrenocortical adenoma, gastrointestinal stromal tumor, hepatocellular carcinoma and schizophrenia. The relationship between SMA and other accompanying diseases was discussed.
