[A multicentric glioma exhibiting three supratentorial lesions]

We reported a multicentric glioma having three separate lesions in the cerebrum. A 75-year old man was hospitalized with progressive disorientation. Computed tomography demonstrated two lesions in the left temporal lobe and the right frontal lobe. Magnetic resonance image disclosed one more lesion in the right occipital lobe. 2-staged operative procedures were performed for the left temporal and the right frontal tumors. It was histologically proven that one was glioblastoma and the other was anaplastic astrocytoma. The patient subsequently underwent radiotherapy and chemotherapy. Most multicentric gliomas are diagnosed in autopsy. Therefore it should be stressed that diagnosis is best made by biopsy or surgery. We discussed what therapy we should use for this fatal disease.
