B cell non-Hodgkin cerebral lymphoma associated with an anaplastic oligodendroglioma.

Primary central nervous system lymphomas and anaplastic oligodendrogliomas are not uncommon; however, no association between the 2 has been documented to date. We describe a unique case, whereby a patient presenting with seizures and slight impairment of higher functions, underwent frontal lobectomy for a mass lesion. The histology revealed dual pathology of anaplastic oligodendroglioma and B cell non-Hodgkin lymphoma. Postoperatively, the patient received whole brain radiotherapy. The patient remained well after 18 months of follow-up with no radiological progression of a known tumor residuum.
