摘　　要：目的 分析MR在颅面部骨纤维异常增殖症的临床价值,为整形外科手术提供影像学参考及借鉴.方法 17例骨纤维异常增殖症的患者常规行磁共振扫描,观察并分析骨纤维异常增殖症的影像学特点,包括病变的总体范围、骨质破坏、软组织受压及重要器官受累等情况.结果 3例患者累及单骨,14例患者累及多骨.MR表现主要以膨胀性骨质改变为主.13例患者出现软组织和肌群异常信号.4例累及鼻部,3例出现眼球受压,3例出现脑膜增厚异常强化.结论 MR能够较为全面准确地反映颅面部骨纤维异常增殖症受侵的骨及软组织范围和程度,为整形外科手术提供参考依据.Objective To investigate clinical application of MRI in analyzing craniofacial fibrous dyspla- sia, providing imaging guide and reference for orthopedic surgery. Methods The routine MR scan was per- formed on 17 patients with facial cranium fibrous dysplasia. The MR imaging features were observed and ana- lyzed, including the overall scope of the lesion of bone, destruction of bone, soft tissue involved, influence of some vital organs. Results Of 17 patients, 3 were with monostotic fibrous dysplasia, the others were with polyostotic fibrous dysplasia. Dilatation and expansion in lesion bones were mainly observed by MR. Abnormal eeho signal in soft tissue and muscles were observed in 13 cases, nose area involved in 4 cases, single lateral eyeball extruded in 3 cases, meningeal thickened and abnormal enhancement in 3 patients. Conclusion The scope and extent of lesions in bones and soft tissue caused by craniofaeial fibrous dysplasia can be demonstrated comprehensively and accurately by MR, whieh provides essential information for orthopedic surgery. It is neces- sary to emphasize the role of MR in eraniofacial fibrous dysplasia.
