[Angiographic findings of tentorial branches of the internal carotid artery in gliomas infiltrating the tentorium (author's transl)].
The tentorial branches, originating from the cavernous portion of the internal carotid artery, showed pathological findings in two cases of brain tumors infiltrating the tentorium: a glioblastoma multiforme of the temporooccipital and basal regions and a medulloblastoma diffusely involving the cerebellar hemisphere, vermis brachium pontis and pons. The value and importance of the tentorial branches are emphasized in the diagnosis of glioma infiltrating the tentorium. The percentage of the visualization and the measurements of the visualized segment of these branches were described using selective internal carotid angiograms by the transfemoral catheter technic on 50 presumably normal adults. The percentage of the visualization of the tentorial branches was 24 percents and the average visualized segment measured 15 mm with a range of 5 to 30 mm on conventional angiograms.
