Non-traumatic myositis ossificans in the paraspinal muscles.

摘要

Myositis ossificans circumscripta (MOC) is a benign condition of heterotopic bone formation that remains difficult to distinguish from soft-tissue and bone malignancies. We describe an unusual case of non-traumatic MOC in the cervical paraspinal muscle. The diagnosis could only be established after surgery and histological examination. We present a review of the literature on this subject and discuss some related features (radiological and histological).
