Motor area cavernous angioma: Case report

Since the introduction of microscopic techniques, it has been thought that radical surgery for cavernous angiomas is recommended even if the lesion is in the brain stem [4]. However, we could not find any cases in which a mot or area cavernous angioma was removed totally with no morbidity. We present a case of motor area cavernous angioma that was removed successf ully, and emphasize the usefulness of sulcotomy technique and magnetoenceph alography (MEG).
