Abstract
A patient with acute isolated rectus superior and levator palpebrae superioris (RS+LPS) muscle complex myositis is presented. A 50-year-old woman presented with a one-day history of left mild palpebral edema, pseudoptosis and orbital pain. On clinical examination, the patient exhibited left palpebral edema and pseudoptosis with preserved levator function and eye movements. Echography and computed tomography (CT) scan findings showed isolated enlargement of the left rectus superior RS/ LPS muscle complex. Oral steroid and NSAID therapy led to complete resolution of all abnormal clinical and echography findings within two weeks. Isolated RS+LPS muscle complex myositis is a rare disease; however, it is important for differential diagnosis in patients with acquired blepharoptosis even if the muscle function is preserved. This was a case of acute isolated RS+LPS muscle complex myositis with preserved muscle function and mild palpebral edema with pseudoptosis and orbital pain as the only clinical manifestations of the disease. The diagnosis was confirmed by pathognomonic echography and CT scan findings of isolated enlargement of the RS+LPS muscle complex and symptomatic improvement on corticosteroid and NSAID therapy.
