摘要

Cerebral arteriovenous malformations (AVM) are congenital lesions in which arteries are connected to veins through an interposed nidus. This aberrant vascular conglomerate acts as a high-flow and low pressure shunt between the feeding arteries and the draining veins thus creating an overload of the venous outflow from the lesion. Patients with AVMs become symptomatic through various manifestations, the most frequent being hemorrhage and seizures. Elevated intracranial pressure and papilledema are unusual modes of presentation which may be consequent to the venous outflow overload caused by the AVM. A cerebrospinal fluid (CSF) fistula secondary to this phenomenon, however, has not been previously reported. The case presented herein concerns such an association.
