Coronary Arteritis with Marked Fibrous Periarteritis: Case Report

A case is presented of a 43-year-old man who died suddenly and unexpectedly from cardiac malignant arrhythmia. Autopsy revealed isolated coronary arteritis involving primarily the left coronary stem and extending into the proximal half of its anterior descending branch. The most striking feature of the disease was marked fibrous periarteritis. Similar changes were present segmentally in the peripheral third of the right coronary artery, and also as small isolated foci of adventitial fibrosis in the aortic base. With some hesitation, we classify the case as coronary Takayasuʹs arteritis.
