Spinal dural arteriovenous fistula with perimesencephalic subarachnoid haemorrhage.
A case is reported of a 66 year old woman presenting with perimesencephalic subarachnoid haemorrhage (SAH) which was caused by a spinal dural arteriovenous fistula at the C1 level. The fistula drained into the venous system of the posterior cranial fossa through a perimedullary vein. The bleeding was thought to result from venous hypertension induced by the fistula. This case may support the hypothesis that perimesencephalic non-aneurysmal SAH can be ascribed to venous bleeding and that venous hypertension is the key to its pathology.
