Dural arteriovenous fistula presenting as brainstem ischaemia.
Dural arteriovenous fistulas presenting with ascending myelopathy are characterised by the presence of an abnormal retrograde drainage through spinal veins. The authors present a case of cranial dural arteriovenous fistula causing brainstem dysfunction secondary to venous hypertension, treated by surgical interruption of the pial venous drainage which resulted in complete clinical and radiological resolution of the brainstem lesion.
