Asymptomatic bilateral pulmonary embolism in Churg-Strauss syndrome.

Churg–Strauss syndrome (CSS) is a systemic small-sized vessel vasculitis, characterised by severe asthma, transient pulmonary infiltrates, and blood and tissue eosinophilia [1]. CSS can affect several organs, including the lungs, heart, kidneys and peripheral nervous system. Anti-neutrophil cytoplasm autoantibodies (ANCA) mainly directed against myeloperoxidase (MPO) are detected in ,40% of patients and are associated with renal involvement. Several studies have focused on venous thromboembolic events (VTE), which are an emerging clinical condition in ANCA-associated vasculitides (AAV) [2, 3]. Herein, we report the case of a patient with newly diagnosed CSS and totally asymptomatic pulmonary embolism, and discuss the features, pathogenesis and management of VTE in CSS.
