Abstract
STUDY DESIGN: Case report and literature review OBJECTIVE: A 5 year old pediatric patient developed scoliosis associated with non-traumatic myositis ossificans in the lumbar region.
SUMMARY: of background data: Although there have been reports in literature of syndromes leading to widespread muscle ossifications resulting in shoulder deformities due to impaired movement in the facet joints, to the best of our knowledge there has been no report of scoliosis associated with myositis ossificans.
METHOD: The case is here presented of a 5 years female paediatric patient who developed scoliosis associated with non-traumatic myositis ossificans in the lumbar region.
RESULTS: On the thoracolumbar radiograph, a hyperintense lesion was seen at right-side L2-L3 level and scoliosis with a Cobb angle of 16.2˚ to the right side. The decision for surgery was taken with the consideration of the existing scoliosis and that the complaints were associated with paraveretebral calcified lesions adjacent to the facet joints. After surgery, it was seen that scoliosis improved.
CONCLUSIONS: Non-traumatic, paravertebral myositis ossificans at an early age is a very rare pathology. Therefore, it must be known that spine deformities such as scoliosis and kyphosis can develop in neglected cases of paravertebral myositis ossificans. In addition, there is a high risk of confusion with malignant pathologies such as osteosarcoma in this localisation. Removal of the mass both eliminates the myositis ossificans causing pain and prevents the development of scoliosis.
