A case of neurofibromatosis associated with a coronary artery aneurysm and myocardial infarction

Abstract

Aneurysms of the aorta, vertebral arteries, carotid artery, thyrocervical trunk, and mesenteric and celiac arteries have been described in patients with neurofibromatosis. These aneurysms may have part of the vessel wall replaced by neurofibromatosis tissue. One previous case reports a coronary artery aneurysm in a patient with neurofibromatosis who suffered a myocardial infarction due to thrombosis formation within the aneurysm. We document a second case of aneurysmal dilatation of a coronary artery in a patient with neurofibromatosis. This patient also had a myocardial infarction in a vascular distribution not involved by the aneurysm. The vascular changes associated with neurofibromatosis are reviewed. Aneurysmal dilatation of the coronary arteries may be a further vascular manifestation of this condition. Copyright © 1992 Wiley Periodicals, Inc.
