A ruptured dissecting aneurysm of the anterior radiculomedullary artery caused by hypoplastic vertebral artery angiography: case report.

ABSTRACT:

Background

Cerebral digital subtraction angiography (DSA) is increasingly utilized in the diagnosis of cerebrovascular disorders. We report a rare case of a ruptured dissecting aneurysm involving the anterior radiculomedullary artery of the cervical spinal cord, precipitated by angiography of a hypoplastic vertebral artery.

Case presentation

Cerebral computed tomography angiography (CTA) revealed severe stenosis of the M1 segment of the right middle cerebral artery in a 70-year-old woman who presented with paroxysmal weakness affecting the left upper and lower limbs. Dual antiplatelet therapy with aspirin and clopidogrel was initiated. On day 3, cerebral digital subtraction angiography (DSA) was performed.
