Primary malignant lymphoma of the brain.
A primary lymphoma in the left temporal lobe of the brain in a 66-year old man is presented. The brain tumor was diagnosed on the basis of clinical symptoms (temporary dizziness, mixed aphasia and right hemiparesis) and repeated CT scanning of the brain. The patient with diagnosed malignant, non-operative brain tumor underwent a series of radiotherapy and steroidtherapy. The patient died twelve months after the first signs and symptoms had occurred. A general autopsy did not reveal any neoplasmatic changes. A macroscopic neuropathological examination showed large tumor's mass in the left temporal lobe which was not separated clearly from its surrounding. A microscopic examination included histopathological (HE, Kanzler-Arendt, Perdrau, PATH, PAS) and immunocytochemical techniques (GFAP, anti-galactocerebroside, LCA, CD45RO, OPD4, CD20). It was found that the examined brain tumor was B-cell malignant lymphoma with the presence of T-cells. Since no changes were revealed in internal organs, the tumor was diagnosed as a primary brain lymphoma.
