title: [Coincidental cerebral aneurysm with brain tumor: report of three cases].
abstract: We report three cases of coincidental cerebral aneurysm with brain tumor. The incidence of such cases has been said to be 0.3 to 0.7% of all brain tumor cases, and, in our experience, has been 0.9% of 315 patients with brain tumor during the last decade. Case No. 1 was a 60-year-old female suffering from subarachnoid hemorrhage followed by left oculomotor nerve palsy due to rupture of left ICPC aneurysm, with left convexity meningioma which was found incidentally during preoperative cerebral angiography. Case No. 2 was a 47-year-old female suffering from headache, right exophthalmos, and bilateral papilledema. Preoperative CT scan and angiographies revealed right sphenoidal ridge meningioma and unruptured right middle cerebral aneurysm. Case No. 3 was a 28-year-old male with acromegaly. Pituitary adenoma and unruptured anterior communicating artery aneurysm were found preoperatively by CT scan and by angiography, respectively. All cases were well diagnosed preoperatively and surgically treated successfully.
