Eosinophilic granulomatosis with polyangiitis related giant coronary aneurysm leading to acute myocardial infarction: a case report

We reported a rare case of an EGPA-related coronary artery aneurysm longitudinally monitored through serial coronary angiography. This case demonstrates that EGPA-related coronary aneurysms may progress despite adherence to therapeutic guidelines and persistently normal eosinophil counts, emphasizing the importance of continuous imaging surveillance and individualized management strategies.
