A 50-year-old male was hospitalized with headache and visual disturbance. Computerized tomography revealed a cystic lesion in the left occipital area as well as a small, hyperdense lesion in the left posterior fossa. On angiograms the left occipitallesion appeared to be a meningioma and the left posterior fossa lesion a venous angioma. In addition, the right carotid angiogram revealed an A_2 aneurysm and the right vertebral angiogram showed a basilar top aneurysm. The left occipital lesion and both aneurysms were treated surgically. The left occipitallesion was diagnosed as meningotheliomatous meningioma. Cystic meningioma is rare, accounting for only 1.2-2.2% of all meningiomas. Also, aneurysms are associated with only 2.5-4% of all brain tumors. To the authors' knowledge, this is the first reported case of the cystic meningioma associated with multiple aneurysms and a venous angioma.
