A case of eosinophilic orbital myositis associated with CSS

Abstract

We report a novel case of eosinophilic orbital myositis associated with Churg–Strauss syndrome. A 56-year-old man with a 20-year history of chronic sinusitis and seasonal allergic rhinitis was admitted because of fever, swelling of cheeks and extremities, diplopia, and eosinophilia. With findings from gadolinium-enhanced FST1WI of the orbits and a muscle biopsy of the skeletal muscle, the diagnosis was made. He was treated with oral corticosteroid, and his symptoms rapidly improved.
