Abstract
We report the clinico radiological presentation of an unusual case of an ossified soft tissue mass in the leg in a 74-year-old man. Calcific myonecrosis is a rare soft tissue condition characterized by calcified mass within a compartment. Differential diagnosis of myonecrosis include myositis ossificans and sarcomas with propensity for extra-osseous calcification like extra-skeletal osteosarcoma, Ewing's sarcoma and epithelioid sarcoma. This entity is a late complication to trauma and prolonged high pressure state within the leg compartments. With imaging alone, the differential of soft tissue sarcoma could be ruled out but typical natural history of disease and radiopathological features aided in the diagnosis.
