An unusual dural arteriovenous fistula in an infant.
Dural arteriovenous fistula, (AVF), a rare entity, presents most commonly in adults. An 11-month-old boy presented with symptoms of congenital toxoplasmosis associated with an extensive dural AVF of the torcular Herophili and bilateral occlusion of the transverse and sigmoid sinuses. His intracranial venous drainage had become rerouted via the cavernous sinuses to the ophthalmic veins. The relationship of toxoplasmosis and sinus thrombosis to the pathogenesis of dural AVF and their clinical and radiological features are discussed.
