title: Clinical presentation and treatment considerations of a ruptured posterior spinal artery pseudoaneurysm.
abstract: Spinal artery pseudoaneurysms are rare vascular lesions with poorly defined natural history, diagnostic paradigms, and treatment strategies. We present a 68-year-old woman with severe back pain and left lower extremity weakness with spinal subarachnoid hemorrhage due to a ruptured T5 region posterior spinal artery pseudoaneurysm, and review issues related to radiologic diagnosis and endovascular and open neurosurgical interventions.
