title: Infiltration of a cerebral artery aneurysm by malignant lymphoma cells with acute rupture: Report of a case.
abstract: A 55 year old woman died suddenly of a ruptured cerebral artery aneurysm. The aneurysm. was infiltrated by cells from a silent, nodular, poorly differentiated lymphocytic lymphoma, which also involved the spleen and abdominal lymph nodes. Compared to leukemias, the incidence of cerebral hemorrhage in non-Hodgkin's lymphomas is exceedingly rare, this being the first case reported in detail. A brief discussion of the etiology of cerebral hemorrhage in lymphomas is provided.
