Angiographic findings associated with intra-axial intracranial tumors.
Although computed tomography and, more recently, magnetic resonance imaging, have supplanted pneumoencephalography and angiography in the initial evaluation of patients with suspected intracranial neoplasms, angiography may still have an important role in the diagnosis and management of such individuals. It can define normal arterial and venous anatomy (important information in planning surgical approaches to some lesions), show vascular abnormalities associated with intracranial tumors, evaluate the integrity of the collateral circulation, incorporate functional testing for eloquent brain in the vicinity of a lesion, and be used in conjunction with the administration of intra-arterial chemotherapy.
