目的：探讨局限性骨化性肌炎的影像学特点,以提高其诊断和鉴别诊断能力。方法回顾性分析45例经病理或临床随访证实骨化性肌炎患者的临床和影像学资料,总结其影像学特征。结果45例骨化性肌炎,肘关节17例,髋关节15例,其他部位13例。X 线平片示34例软组织内层状或片状高密度骨化影,其中12例出现“蛋壳”样骨化。CT 显示较 X 线平片更为清晰的肿块内骨化影。MRI 显示18例软组织肿块并周缘水肿；3例肿块内广泛骨化,周缘无水肿。SPECT/CT 显示12例软组织内显像剂异常团状浓聚,其中5例浓聚范围大于骨化范围,4例浓聚范围小于骨化范围。结论局限性骨化性肌炎有一定的影像学特征,多种影像学综合应用并结合临床可全面显示其病程演变,提高准确诊断率。

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.
