Area of Science:

Cardiology
Pathology
Radiology

Background:

Coronary artery aneurysms (CAAs) are uncommon vascular abnormalities.
Massive CAAs can present with complex and atypical clinical manifestations.

Observation:

A 62-year-old male presented with findings suggestive of a cardiac tumor.
Pathologic and echocardiographic examinations revealed a massive, thrombosed right coronary arterial aneurysm.

Findings:

The aneurysm destroyed a pulmonary valve cusp, leading to severe pulmonary stenosis.
It caused right ventricular outflow tract narrowing and tricuspid valve cusp fixation.

Implications:

This case underscores the importance of considering CAAs in the differential diagnosis of cardiac masses and outflow tract obstruction.

Accurate diagnosis is crucial for appropriate management and preventing complications.
