[The association of cerebral aneurysm with malignant brain tumor--report of a case (author's transl)].

A rare case was reported in which a brain tumor was associated with a cerebral aneurysm. A 59-year-old woman was admitted with right spastic hemiparesis and motor aphasia. She was in somnolence and complained of headache. She had two attacks of loss of consciousness about 12 years previously. Since then she had right spastic hemiparesis and motor aphasia as sequelae. Preoperative CT scan and carotid angiograms showed a malignant brain tumor in the left temporal region and an anterior communicating artery aneurysm. Operation was performed in one stage. At first the neck of the aneurysm was clipped by right sphenoidal approach and the tumor was partialy removed by left temporal approach. The histological diagnosis was glioblastoma multiforme. The cerebral aneurysm associated with brain tumor should be treated as soon as possible. The operative result in our case was good.
