[A case report: Osler-Weber-Rendu disease with cerebral aneurysm, cerebral arteriovenous malformation and pulmonary arteriovenous fistula (author's transl)].

Osler-Weber-Rendu disease (hereditary hemorrhagic telangiectagia) is a rare vascular disorder which is characterized clinically by inherited telangiectasia of skin, mucous membrane and recurrent hemorrhage. However, it is not rare that various organs, for instance, lung, liver, intestine are inflicted by vascular disorder in this disease, and central nervous system is not an exception. A 60-year old man was examined for repeated epistaxis and an episode of subarachnoid hemorrhage. In this case, left middle cerebral artery aneurysm, arteriovenous malformation fed by left posterior cerebral artery and pulmonary arteriovenous fistula were revealed by angiography and computerized tomography. It is interesting that various vascular disorders were found in one case.
