title: Traumatic myositis ossificans of the masseter muscle: a case report with conventional and advanced imaging features.
abstract: Myositis ossificans of the head and neck is a rare heterotopic, nonneoplastic bone formation within a muscle. Traumatic myositis ossificans (TMO), also known as myositis ossificans circumscripta, is the most common form, resulting in muscle ossification after trauma or hematoma. This article presents a case of TMO in the left masseter muscle of a 26-year-old male patient who suffered from epilepsy. The various types of myositis ossificans, its epidemiology, pathogenesis, differential diagnoses, and various treatment modalities are outlined.
