Myositis ossificans is a benign condition, essential to know because the presence of ossifications of the soft tissues adjacent to the bone, always makes one fear a neoplastic localization in a young patient. We report in this study a rare case of traumatic circumscribed myositis ossificans of the thigh. Imaging plays an important role in the positive diagnosis, the differential diagnosis and the follow-up of the characteristic three-phase evolution of MOC. However, this pseudotumor may appear clinically and radiologically as a malignant tumor, a thorough knowledge of clinical and morphological study is necessary to differentiate this lesion from a soft tissue malignancy.
