Eosinophilic myocarditis as a first presentation of eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome)

We present the case of a 28-year-old man who presented with chest pain and elevated cardiac biomarkers, with no evidence of acute ischaemia. He had a pronounced eosinophilia, abnormal echocardiographic, cardiac MRI and CT findings. He underwent transbronchial biopsy of carinal lymph nodes and of lung parenchyma. Endomyocardial biopsy yielded an eosinophilic infiltrate. He was treated with high dose glucocorticoids and made a rapid recovery. Testing for FIP1L1-PDGFRA and other BCR-ABL1 mutations was negative. Ultimately, he was diagnosed with eosinophilic granulomatosis with polyangiitis, also known as Churg-Strauss syndrome.
