The angiographic semiotics of tumors of the brain and its membranes
Radiation semiotics of brain tumors and its membranes is presented based on data from X-ray imaging and interventional contrast angiography of the cerebral vessels of 48 patients (32 males, 16 female) aged 20 to 50 years. Brain tumors were observed with the highest frequency at the age of 30-40 years (67%). Of the total number of indentified brain tumors 64% were arahnoendotheliomas (meningiomas) and 36% were intracerebral (I.I. Kamalov, 1993). The most frequent localization of meningiomas were the postfrontal, parietal and parasagittal regions. Intracerebral tumors were more common in the frontal, parietal, occipital and temporal lobes. Cerebral angiography was conducted to patients by indication, using the Seldinger technique for catheterization. Angiographic semiotics of the brain and is membranes and differential diagnosis was conducted thoroughly. Thus, cerebral angiography is an accurate, informative and in some cases, an indispensable diagnostic tool.
