BACKGROUND: Aneurysms of the spinal artery are exceedingly rare. We report on the first case of a pathologically proven aneurysm arising from the feeding pedicle of a perimedullary arteriovenous fistula (AVF). CASE DESCRIPTION: A 42-year-old man presented with subarachnoid hemorrhage (SAH) and spinal angiography demonstrated a thoracic perimedullary AVF fed by the left T8 intercostal artery that also harbored a spinal aneurysm. He underwent laminectomy 18 days postonset. The aneurysm was resected and the fistula was interrupted. CONCLUSION: For appropriate treatment planning, it is necessary to rule out the presence of aneurysms on the feeding vessel in patients with spinal perimedullary AVF who present with SAH.
