We report a case of a 29-year-old man who had been a victim of a public road accident. Four weeks later, the patient developed an isolated right thigh mass located ventrally in the distal one-third of the thigh. The mass was painful and associated with fever and inflammatory syndrome. Plain radiographs showed a bilateral calcified thickening of soft tissues with well-defined bony margins. Ultrasound objectified diffuse calcifications of soft tissues.CT scan-confirmed the diagnosis of myositis ossificans circumscripta, showing a bilateral thickening of the vastus intermedius chief of the quadriceps dotted with calcifications, extending along the femur axis. These calcifications have well-defined bony margins separated from the periosteum by a lucent zone.
