We examined two patients with acute orbital myositis associated with orbital hemorrhage and eyelid ecchymosis. Both patients were young women (aged 22 and 30 years) who had painful proptosis, diplopia, and computed tomographic evidence of single extraocular muscle involvement with spillover of inflammatory edema into the adjacent orbital fat. ⋯ Both patients were treated successfully with high-dose systemic corticosteroids. Some cases of idiopathic orbital inflammation may be related to preexisting vascular anomalies or orbital phlebitis.
