AbstractIn a 52-year-old woman, spinal arteriovenous malformation (AVM) has been associated with what has been known as Foix-Alajouanine syndrome. The pathophysiology of the AV fistula is probably related to increased venous pressure from the AVM plus thrombotic process. The most common initial symptoms are sensory disturbance, pain and leg weakness. Definitive diagnosis of spinal AVMs requires radiographic demonstration of the vascular anomaly. Nevertheless, in this case, suggestive defects of malformations could not be seen, in contrast to the MRI findings and macroscopical and anatomical-pathological lesion. These findings rise our attention, about the need to keep in mind the clinical suspicion of AVM in cases of back pain and motor deficit, and an early surgical conduct in this situation.
