Foix–Alajouanine syndrome, also called subacute ascending necrotizing myelitis,[1] is a disease caused by an arteriovenous malformation of the spinal cord.

[2] In particular, most cases involve dural arteriovenous malformations that present in the lower thoracic or lumbar spinal cord.

Clinically, the patient may present with neurological symptoms such as numbness, weakness, loss of reflexes, or even sudden or progressive paralysis.

A spinal MRA will serve as a superior imaging technique to visualize the extent of the arteriovenous malformation within the cord and may be especially useful if surgical treatment is attempted.

[7] In either case, physical therapy will be an important part of the recovery process in helping the patient regain strength and coordination.
