Abstract

Myositis ossificans circumscripta is a pathological condition characterized by formation of bony tissue within the skeletal muscles following repeated trauma. A case of myositis ossificans circumscripta of the
supra-orbital region in a 25-year-old man is presented and the pertinent literature is reviewed. To the best our knowledge this benign lesion has not been reported previously in the orbital region the world literature. Clinically the patient presented with a swelling and proptosis of the right eye. Radiologically there was a rounded opacity with well defined margin. Lesion was initially misdiagnosed as a fibroosseous lesion; however microscopic examination indicated matured myositis ossificans. Lesion was excised via a bicoronal flap. Careful clinical, radiological and pathologic evaluation is required to make this uncommon diagnosis in an unusual location such as the supra-orbital region to avoid unnecessary surgical mutilation of the patient
