Abstract

Background. Aneurysms of the extracranial vertebral artery are rare and can provide a diagnostic and therapeutic challenge. Methods. We reviewed the clinical history of a patient presenting with cervical radiculopathy, who harboured an extracranial vertebral artery aneurysm eroding the cervical spine. Results. CT Angiography and MR Angiography set the diagnosis, by revealing a left C5-C6 vertebral artery aneurysm with cervical root impingement. Bony reconstruction depicted enlargement of the C6 transverse foramen and a marked enlargement of the C6-C7 intravertebral foramen. The lesion was treated by intravascular proximal vertebral artery occlusion. Conclusions. Extracranial vertebral artery aneurysms require a high index of clinical suspicion. This is the first report of a vertebral artery pseudoaneurysm presenting with bony erosion, which supports a less minacious portrayal of vertebral artery aneurysms.
