Subacute Necrotic Myelitis

Subacute necrotic myelitis (Foix-Alajouanine syndrome) is a progressive, necrotizing myelopathy due to spinal vascular abnormality/venous congestion, causing progressive paraparesis, sensory level, and bladder dysfunction over weeks. It is rare. Treatment: identify and treat the vascular cause (angioplasty/surgery when possible), supportive care, and rehab; prognosis depends on prompt treatment.

Common Symptoms

Progressive paraparesis; sensory level; bladder dysfunction; subacute progression; back pain

Causes and Pathogenesis

Spinal vascular malformation/venous congestion causes progressive ischemic/necrotic myelopathy.

Treatment

Treat vascular cause (embolization/surgery); supportive; neurorehab; bladder care

Preventive Measures

Vascular workup; early treatment.
