A 62-year-old subhemophiliac patient developed a severe iliopsoas hemorrhage following minor trauma. CT scanning revealed a large iliopsoas hematoma and intraperitoneal hemorrhage. Angiography demonstrated active bleeding from the fourth right lumbar artery, a complication of an iliopsoas hematoma not previously described.
