Spinal arteriovenous malformations are rare abnormalities that are difficult to recognize and treat. They represent 3.3 to 11 percent of all spinal cord tumours. The signs and symptoms most commonly encountered consist of progressive upper and lower motoneuron deficits, eventually leading to severe crippling disability. Ten to twenty percent of these patients will present with an associated spinal deformity that must be differentiated from idiopathic scoliosis. The case presented in this paper illustrates the diagnostic difficulties when spinal arteriovenous malformation is associated with scoliosis.
