Angiographic demonstration of a spinal epidural arteriovenous malformation. Case report.
A 16-year-old boy presented with acute midline thoracic pain followed by rapidly progressive paraplegia. The initial neurological examination demonstrated a complete sensory and motor paraplegia, which significantly improved spontaneously over the following 2 days. Magnetic resonance imaging revealed a posterior epidural hematoma extending from the T-4 to T-6 vertebrae, and spinal angiography demonstrated an arteriovenous malformation (AVM) with a nidus of abnormal epidural vessels at the level of the T-5 vertebra, which was confirmed surgically. This case represents one of the first reports of a spinal epidural AVM confirmed by angiography.
