[Value of the angioscan in the etiological diagnosis of cerebromeningeal hemorrhage].
Etiologic diagnosis of cerebromeningeal hemorrhage was suspected on CT scan without contrast imaging as a function of distribution of cisternal hyperdensities and/or topography of intracerebral hematomas and/or distribution of parenchymatous hypodensities. It was established in 90% of cases by results of angioscan (type and site of vascular malformation causing the cerebromeningeal hemorrhage are defined with this percent exactitude). Cerebral arteriography provides indispensable precise morphologic data on the vascular malformation: exact site of aneurysm or arteriovenous malformation, orientation of the aneurysm and presence or absence of a collar. It is therefore irreplaceable and will be guided by data from the angio-CT scan.
