[A case of spinal cord angioma with selective damage of the peripheral motor neurons]

A 47-year-old man is reported who had an extensive arteriovenous angioma of the spinal cord confirmed during operation. The patient had an atypical symptom complex, with clinically evident deep flaccid paresis of lower extremities without pyramidal signs, sensory disturbances and sphincter disturbances. The anomaly causing a steal mechanism led to ischaemia of the anterior horns of the cord.
