Idiopathic orbital myositis is an autoimmune disease which is rarely seen among children. Corticosteroids are the mainstay of treatment, inducing rapid and dramatic reversal of inflammatory findings. An extended taper of the corticosteroids is advised to prevent rebound inflammation. In this case report, we present an 11-years-old girl who admitted to our clinic with acute onset orbital pain, periorbital edema and diplopia and who was finally diagnosed as idiopathic orbital myositis.
