Abstract

Myositis ossificans is an ossifying inflammatory lesion occurring within skeletal muscle. Myositis ossificans usually arises in the large muscles of the extremities and this lesion is characterized by progression of mineralization from periphery to center. In the early phase, myositis ossificans simulates malignant soft tissue tumor without dense mineralization. Traumatic myositis ossificans in rectus abdominis muscle has been reported worldwide. The radiologic findings of early active myositis ossificans in rectus abdominis muscle are ill defined heterogenous hypoechoic mass on US, hemorrhage, early strong enhancement and early peripheral mineralization on CT and MR.
