Radiation myelopathy is a rare but potentially devastating complication of therapeutic irradiation. Subacute (transient) myelopathy is the most common form, consisting of paresthesias or "electric shock" sensations radiating down the spine and the limbs, which typically resolves gradually over one to nine months. Delayed injury to the spinal cord typically presents as the more rare chronic progressive myelopathy, which is usually irreversible, and presents with numbness or dysesthesias in the legs, followed by weakness and sphincter dysfunction.
