title: Angiography and computed tomography in the diagnosis of primary lymphoma of the brain.
abstract: Three patients with primary lymphomas of the brain are presented. The angiographic and computed tomographic (CT) appearances resembled the few cases reported previously. In all three cases angiography showed avascular tumours with little vessel displacement or involvement whereas the CT scans showed large strongly and homogeneously enhancing tumour masses. Neither method alone gives pathognomonic appearances, but taken together angiography and CT should suggest the diagnosis of this rare tumour.
