[Case Report] Eosinophilic myocarditis: a paraneoplastic event

In September, 2014, a 55-year-old woman presented to our emergency department with a 2 month history of worsening dyspnoea. She was a smoker with a 19 pack-year history but no other risk factors for pulmonary or cardiovascular disease. On examination her blood pressure was 90/60 mm Hg, heart rate 130 beats per min, and oxygen saturation 92% on room air. She had jugular venous distension and reduced breath sounds bilaterally but no pitting oedema of the legs. Laboratory tests showed an increased leucocyte count (18·9 × 109/L) with neutrophilia (79%) and normal eosinophils, raised C-reactive protein (36 mg/L), and raised troponin T (354 ng/L).
