Spinal angiomas as a cause of non-traumatic paraplegia: case report.

A case is presented of a 17-year-old boy who developed paraplegia after a sudden low back pain, like a 'stab in the back', with radicular radiation into the lower limbs. No trauma preceded the onset of symptoms. The diagnosis was finally made by neuroradiological investigations (magnetic resonance imaging (MRI), myelography and CT-scan). A review of the physiopathology of spinal angiomas, extra and/or intramedullary, by exclusion of vertebral (haem) angiomas, is made.
