title: Spontaneous internal oblique hematoma successfully treated by transcatheter arterial embolization.
abstract: Abdominal wall hematoma is an uncommon cause of acute abdominal pain. We report a case of internal oblique hematoma caused by rupture of the subcostal artery in a 57-year-old woman. Ultrasonography (US) showed a hypoechoic mass in the right lateral abdominal wall. Contrast-enhanced computed tomography (CT) showed a large soft tissue mass with extravasation of contrast medium located in the right internal oblique muscle. Angiography showed contrast extravasation from the subcostal artery, and transcatheter arterial embolization was performed successfully.
