Case report: spontaneous thrombosis of a spinal dural AVM (Foix-Alajouanine syndrome)--magnetic resonance appearance.

We describe a patient with a classical presentation of a spinal dural arteriovenous malformation which probably underwent spontaneous thrombosis. This is known as the Foix-Alajouanine syndrome. The diagnosis was not made in this patient until after cord infarction had occurred. The clinical and radiological features of spinal vascular malformations are reviewed because prompt treatment may halt or even reverse their neurological manifestations.
