title: Symptomatic Spinal Migration of Subarachnoid Hemorrhage due to Ruptured Intradural Vertebral Artery Aneurysm.
abstract: A 55-year-old patient was admitted to the hospital with severe acute back pain. Thoracolumbar magnetic resonance (MR) imaging showed hemorrhage in subarachnoidal-subdural space. On cranial MR imaging and MR angiography, an aneurysm was suspected in the V4 segment of the right vertebral artery. Angiography showed a fusiform dissecting aneurysm in the V4 segment of right vertebral artery. The final diagnosis was ruptured V4 segment aneurysm with subsequent symptomatic migration of hemorrhage into the spinal subarachnoidal-subdural space. The patient was treated endovascularly by coil occlusion of both the aneurysm and vertebral artery. This rare cause and possible mechanisms for spinal migration of intracranial hemorrhage after aneurysmal rupture is discussed.
