title: Spinal aneurysm of the lateral sacral artery. Case report.
abstract: Spinal aneurysms are rare, and those not associated with either an arteriovenous malformation or coarctation of the aorta are particularly rare. In this report, the authors present a case of spinal aneurysm involving the lateral sacral artery. The aneurysm presented as a cauda equina syndrome 6 years after the patient underwent a renal transplant contralateral to the side of the aneurysm parent vessel. To the authors' knowledge, only one similar case has been previously reported. They conclude that spinal aneurysms should be included in the differential diagnosis of an extramedullary spinal mass lesion.
