Computerized tomography findings in multifocal glioma.

Six patients with multifocal glioma are presented. Computerized tomography revealed multiple, discrete, contrast-enhancing lesions in the cerebral hemispheres, suggestive of multiple intracranial metastases. The most accessible lesion was resected at craniotomy in each patient, confirming the diagnosis of primary malignant glioma. Postoperative radiation therapy and chemotherapy were instituted according to current protocols. Since neuroradiological studies may not allow distinction of multifocal glioma from multiple brain metastases, surgical biopsy is suggested in those patients who have no history of cancer.
