Bilateral orbital myositis and dacryoadenitis after sclerosing mediastinitis

Abstract

A 49-year-old male with a history of sclerosing mediastinitis presented with complaints of bilateral (left greater than right) eye pain and redness for 3 weeks. Clinically, the patient demonstrated signs of bilateral dacryoadenitis and myositis. CT confirmed enlargement of both lacrimal glands and lateral rectus muscles. Due to the relationship between sclerosing mediastinitis and orbital inflammatory pseudotumor (OIP), the patient was treated with oral prednisone with a brisk response. OIP is common in ophthalmic practice and treating physicians should be aware of the associations with systemic disease processes.
