title: [A case of giant aneurysm at the posterior cerebral artery (author's transl)].
abstract: Giant aneurysm of the posterior cerebral artery was very rare. The authors could seek only 6 cases in published literature. We experienced one case of the giant aneurysm at the posterior cerebral artery. The case was 25 years old female. She occasionaly complained of headache and nausea for 4 years before administration. Cerebral angiogram revealed a giant aneurysm of the right posterior cerebral artery with slightly dilated ventricle. CT scan revealed a ring shape high density area and its high density area enhanced by Conray infusion. A clipping of posterior cerebral artery at the just proximal point of the aneurysmal neck was done, because adhesion of the aneurysm to the brain stem was very tight and the aneurysmal neck was very broad. After the operation, giant aneurysm was not seen on both angiogram and CT scan. Patient did not complain of headache any more and any defect of the visual field.
