Abstract

Background: Coronary artery aneurysms are not uncommon vascular anomalies, but giant coronary artery aneurysms mimicking cardiac tumors are extremely rare and easily misdiagnosed as tumors. The management and prognosis are not well defined.

Case report: We describe a case of a 50-year-old woman, who had a transthoracic echocardiogram that suggested a cardiac tumor in the right ventricle adjacent to the tricuspid valve and without ventricular wall akinesia. Her medical history was unremarkable, and she had no obvious symptoms. A transesophageal echocardiogram and computed tomography angiogram examination suggested the tumor-like structure was a giant coronary aneurysm, originating from the distal portion of right coronary artery. The patient underwent surgical intervention and recovered uneventfully. Histopathology
of the excised aneurysm showed fibrous tissue hyperplasia with collagenization and calcification in the wall of the artery.

Conclusion: Giant coronary artery aneurysms resembling heart tumors are extremely rare. Differentiating them from cardiac tumors can sometimes be difficult. This rare case emphasizes the importance of combining multiple imaging methods, which helps make accurate diagnosis. For treatment, surgical intervention may be the appropriate therapeutic strategy for the rare lesion.
