[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.
