Incidental tumor blush of a mass encasing right coronary artery

Abstract

A 64-year-old woman admitted to our hospital (a tertiary care center) with symptoms of chest pain and dyspnea of functional class 2. Coronary angiography showed no stenosis, but injection of right coronary artery (RCA) showed suspicious shadow around the vessel. Computed tomographic angiography was done for further evaluation of probable iatrogenic aortic dissection, and incidental tumor was found encasing RCA proximal anterior to its origin of aorta. Magnetic resonance imaging suggested lymphangioma as the most probable cause (based on the tissue characterization criteria). According to benign nature of the tumor, follow-up by imaging was recommended.
