Abstract:
Objective To study the imaging characteristics of localized myositis ossificans for improving its diagnosis and differen-tial diagnosis ability.Methods The Clinical and radiographic data of 45 cases with localized myositis ossificans proved by pathology or clinical follow up were analyzed retrospectively,summarize its imaging features.Results Of the 45 cases,1 7 cases occurred in the elbow joint,1 5 in the hip joint,13 in the other parts of the body.X-ray showed lining or lamellar high-density ossification in soft tis-sues in 34 cases,of those 12 cases with “shell”ossification.Compared with the X-ray,CT showed more clear ossification.MRI showed the soft tissue mass with peripheral edema in 18 cases;3 cases obvious ossification,no edema around.SPECT/CT showed abnormal imaging agent concentration in soft tissue within 12 cases,of those 5 cases concentration range greater than the range of ossification,4 cases concentration range less than the range of ossification.Conclusion Localized myositis ossificans have certain im-aging characteristics.Integrated application of a variety of imaging combined with the clinical can fully display the evolution of the disease,and improve its diagnosis rate.
