Giant coronary aneurysm in Churg-Strauss syndrome

A 64-year-old male with Churg-Strauss syndrome (CSS) presented with worsening dyspnoea without chest pain besides having long-standing asthma. There were no cardiovascular risk factors. The electrocardiogram showed signs of prior anterior infarction. Echocardiography demonstrated severely depressed left ventricular function (ejection fraction 30%). Multislice cardiac computed tomography revealed a giant coronary aneurysm (Figure 1A and Figure 1B) of the left circumflex coronary (LCX) artery of 4 cm diameter with mural thrombi (Figure 1B) and also aneurysmatic changes of the right coronary artery (RCA) with proximal occlusion (Figure 1 A). Coronary angiography showed aneurysmatic changes
