Myositis ossificans (MO) is a heterotopic bone formation in muscle tissue that usually occurs due to trauma. The reported without trauma of it is rare. In this case, MO was detected in the supraclavicular portion of the plexus brachialis and between the musculus (m.) scalenus anterior and m. scalenus medius. A previously described case was not found in the literature.
