[A case of aortitis syndrome associated with basilar aneurysm (author's transl)].

A case of aortitis syndrome (pulseless disease) associated with basilar aneurysm is reported. This patient was 52-year-old woman suffering from pulseless disease for past fifteen years. She was admitted to our hospital with severe headache, nausea and vomiting. Four vessel angiograms revealed an aneurysm of the basilar artery and occlusion of the right vertebral artery. The internal carotid artery in the left side and the subclavian artery in the right side were not demonstrated even by the serial aortography. As regard to the pathogenesis of cerebral aneurysms associated with aortitis syndrome, questions are in discuss whether the aneurysm is of congenital nature or the result of acquired arteriosclerosis due to aortitis syndrome. In addition, the rupture mechanism of basilar aneurysm associated with aortitis syndrome is discussed.
