Two cases of intracranial malignant lymphoma--clinical and pathological differences in intracerebral infiltration between primary intracranial lymphoma and systemic malignant lymphoma.

Abstract

Intracranial malignant lymphoma accounts for 0.6 to 3.2%of the total cases of cerebral tumors, and the number of cases reported has increased in recent years. The authors experienced simultaneously two cases; one a cerebral primary malignant lymphoma found in the cerebral basal ganglion and the other probably a result of an intracerebral infiltration of the general malignant lymphoma. The patients were males, aged 33 and 43 years when initially attacked by the diseases. Their initial symptoms and clinical progress closely resembled each other and surgical observations were also similar. In neuro-radiological terms, only a difference in vascularity was observed in the cerebral angiogram but was not observed in the CT scan. With regard to the question of whether it is possible that the discrimination can be achieved clearly in each lymphoma, we have discussed the clinical and pathological differences between the two patients with other reports.
