A 40-year-old male was hospitalized for recent onset of focal epilepsy. Computed tomography revealed a large, convexity mass in the left hemisphere, which was diagnosed as a meningioma and was deemed the cause of the focal seizures. In addition, there was a small area of ring-like enhancement in the right occipital lobe. The occipital lesion, histologically diagnosed as anaplastic glioma, progressively enlarged and eventually caused the patient's death. The presence of multiple, diverse primary brain tumors is infrequent in patients without phakomatosis. Although meningioma may possibly be induced by another, adjacent tumor or by cranial irradiation, in this case the coexistence of the two tumors is thought to have been incidental because both glioma and meningioma have a high incidence and because they were separate.
