[Spinal meningeal hemorrhage due to tumors: a report on 5 cases with arteriography (author's transl)].

Meningeal hemorrhages in 5 patients with tumors of the cauda equina are reported. In each case there were signs from the brain area which led to a false diagnosis of ruptured intracranial aneurism, before attention was drawn to the cauda equina by a relapse with hemorrhage or other signs. The value of medullary arteriography for positively diagnosing cauda equina tumors, and their differential diagnosis from medullary arteriovenous malformations--principal cause of spinal meningeal hemorrhages--is discussed, as well as the necessity for systematically evoking this topography in children and young adults when arteriographic exploration is negative.

Subarachnoid hemorrhage due to intraspinal tumors.

Five cases of subarachnoid hemorrhage arising from an intraspinal tumor are presented, Three of these were ependymomas in the region of the cauda equina. One was a neurofibroma at L1. The fifth was a hemangioblastoma in the upper lumbar region.
