Thymomas are usually tumors with a good prognosis but with potential to invade nearby structures. We report a case of a 56-year-old woman previously diagnosed with an invasive thymoma that came to the emergence room with symptoms of acute coronary syndrome. After a coronary computed tomography angiography, it was seen that the tumor was invading the myocardial and it was irrigated by the left circumflex coronary and its branches. Considering her poor prognosis, it was decided not to make further interventions. This case highlights a unique and rare case of an unresectable thymoma that was invading the myocardium and it was irrigated by the left circumflex coronary and its branches, causing typical angina due to compromised coronary blood flow by the mass causing ischemia.
