[Intracranial aneurysm and coronary ectasia].
Coronary aneurysms are uncommon and can exceptionally be associated with other aneurysmal localizations. A 34 year-old man with a history of aneurysm of the coronary arteries revealed by myocardial infarction without a wave six months earlier, presented cerebral hemorrhage secondary to an aneurysmal rupture of the anterior communicating artery. Other aneurysmal localizations such as the abdominal artery, pulmonary artery, hepatic artery, popliteal artery, coronary venous system or the left ventricle have been associated with coronary artery aneurysm. Only one case of coronary and cerebral aneurysm has been previously reported in the literature in an 8-year-old child with X-linked lymphoproliferative syndrome and EBV-induced infectious mononucleosis. Our case suggests that systemic aneurysmal disease may be a clinical entity and that cerebral angiogram should be discussed in patients with a coronary artery aneurysm.
