Foix-Alajouanine Syndrome Mimicking Longitudinally Extensive Transverse Myelitis

Abstract

Foix-Alajouanine syndrome is an arteriovenous malformation causing subacute congestive myelopathy that can lead to progressive paraplegia. It typically affects the lower thoracic and lumbosacral levels. Arteriovenous fistula (AVF) leads to increased venous pressure, decreasing the arteriovenous pressure gradient and leading to a decrease in spinal cord perfusion, oedema and necrosis. Early recognition and surgical intervention can result in a good prognosis.
