[Subarachnoid hemorrhage caused by spinal arteriovenous angioma. Diagnostic difficulties and therapeutic possibilities].

In a young patient with spinal angioma, the diagnosis was not established until the fourth episode of bleeding. Exemplified by this case, the clinical symptomatology of spinal subarachnoid hemorrhage is described, and the diagnostic and therapeutic procedures are reviewed. In patients with SAH it is necessary to look for spinal symptoms, especially if cerebral angiography proves negative. In diagnosing a spinal SAH priority should be given to myelography and/or MRT, followed by spinal angiography.
