Myositis Ossificans

Myositis ossificans of the platysma mimicking a malignancy: a case report with review of the literature

“…Chuah et al 19 reported that the erythrocyte sedimentation rate and alkaline phosphatase could be elevated in the acute phase of traumatic MO. While these tests were not carried out in this patient, they are non-specific with wide variations based on age and sex, especially the alkaline phosphatase levels found in growing children 20 such as this 11-year-old girl.…”

“…Our patient had surgical excision of a portion of the involved platysma muscle with complete resolution of the symptoms within 6 months. Conservative measures such as rest, analgesics, physical therapy, and extracorporeal shock wave therapy have been satisfactorily used in other non-facial body parts 19 23 . It is possible that following the diagnosis of traumatic MO, surgery can be delayed if symptoms are not severe.…”

Myositis ossificans of the serratus anterior as a rare complication of massage: a case report

“…In this case, the patient did not have any brain or spinal cord injury. Traumatic myositis ossificans is secondary to trauma, surgery, or inflammation of a heterotopic ossification; it is a common complication of bone and joint diseases [ 3 ]. Hence, the cause of this patient’s reported condition might be due to a long-term (2 years) aggressive nape massage, which could have led to repetitive powerful manipulation injury to the serratus anterior below the collarbone and repetitive muscle bleeding and inflammation forming the adhesions and ossification gradually.…”

Imaging review of normal anatomy and pathological conditions involving the popliteus

“…In the mature stage there is further osseous consolidation resulting in a densely calcified lesion usually parallel to the long axes of adjacent bone. 14,15 Differentials for MO include infection particularly in the early stage when muscle swelling and inflammation are the predominant features. Conversely chronic abscess can also have associated peripheral calcification.…”
