Churg-Strauss syndrome with broad spectrum clinical presentations: a report of 3 cases

Similar to CSS, idiopathic hypereosinophilic syndrome causes multiorgan involvement, but is can be distinguished by a peripheral blood eosinophil count > 1500/ mm3 for more than 6 months [18]. [...] clinical pictures, laboratory findings and course of illness can differentiate idiopathic hypereosinophilic syndrome and CSS [7]. [...] we believe CSS can be diagnosed by an accurate history, clinical examination and laboratory tests with no need for invasive procedures such as lung biopsy.
