Cardiac involvement of eosinophilic granulomatosis with polyangiitis is a rare but life-threatening complication. We present a case of eosinophilic granulomatosis with polyangiitis with moderately impaired ventricular function forming a ventricular thrombus. Pathological assessment of endomyocardial biopsy specimen revealed aggregated eosinophils in the subendocardium, suggesting ventricular endothelial damage leading to thrombus formation.
