Giant coronary artery aneurysm mimicking a compressive cardiac tumor

Giant atheromatous coronary aneurysms mimicking a cardiac tumor remain exceptional. We report the case of a patient who experienced a severe inferior myocardial infarction related to a giant thrombosed coronary aneurysm masquerading a cardiac tumor and compressing right cardiac cavities with mechanical detrimental consequences on tricuspid, mitral and aortic valvular competence. The contribution of imaging was essential to assess diagnosis, understand the physiopathogeny of myocardial and valvular consequences and plan the optimal surgical strategy.
