Abstract:
A case of paravertebral, non-traumatic myositis ossificans in a 4.5 year-old boy is reported. Infectious spondylitis and osteosarcoma were considered before the diagnosis was established on the basis of histological examinations of a biopsy performed during excision. A group G beta hemolytic streptococcus was isolated from the biopsy, suggesting an infectious etiology which has rarely been reported. The child appears to be completely cured one year after excision.
