Churg-Strauss vasculitis presenting with steroid-responsive left ventricular cardiac mass

A 35-year-old black Saudi man, with a known case of bronchial asthma and allergic rhinitis since childhood, presented with joint pain and swelling, orthopnoea, paroxysmal nocturnal dyspnoea and lower extremity oedema. On examination, we found jugular venous distension, bilateral basal crepitation, wheezing and diffuse synovitis. Investigations were notable for peripheral blood eosinophilia, pericardial effusion and elongated structure in the left ventricular outflow tract on echocardiography, mediastinal and hilar lymphadenopathy and right upper lobe infiltrate on high-resolution CT scan. Pulmonary infiltrate biopsy confirmed eosinophilic vasculitis. Intracardiac mass resolved shortly after pulse steroids indicating an inflammatory mass.
