title: Nontraumatic rupture of lumbar artery causing an intravertebral body pseudoaneurysm: treatment by transcatheter embolization.
abstract: We report a case of nontraumatic rupture of the lumbar artery that led to a pseudoaneurysm in the vertebral body and massive retroperitoneal to retropleural hematoma. The pseudoaneurysm was successfully treated by endovascular embolization. To our knowledge, idiopathic rupture of the lumbar artery has been reported in a limited number of cases and pseudoaneurysm formation in the vertebral body has not been presented in the literature. The etiology of hemorrhage has been discussed based on CT, MRI, and three-dimensional rotational angiography.
