摘要
目的:分析颅面骨骨纤维异常增生症(fibrous dysplasia of bone,FDB)患者的X线平片和CT的影像学特征,比较两者在颅面骨FDB诊断中的价值。方法:10例经手术病理证实的颅面骨FDB患者均行普通颅面骨X线平片检查,其中4例同时行CT扫描,对其X线平片和CT图像表现进行回顾性比较、分析。结果:10例FDB患者中,单骨型4例,多骨型6例;根据影像学表现又可分为致密型2例、磨玻璃型3例、囊型2例和混合型3例;其中1例X线平片与CT诊断间定位及FDB分类均相符合;2例X线平片与CT诊断间定位不符合,FDB分类相符合;1例X线平片与CT诊断间定位及FDB分类均不相符合,CT在病变定位和FDB类型诊断方面更准确。结论:X线平片检查虽能较好地诊断颅面骨FDB,而CT对于多骨型FDB可准确定位,并可利用高分辨率的图像进行分型,较普通X线平片检查更有诊断价值,同时也更有助于FDB与骨化性纤维瘤间的鉴别诊断。
Objective To analyze the conventional X-ray and CT features of fibrous dysplasia of craniofacial bones （FDB） and compare the diagnostic value of the two examination methods. Methods Ten cases of fibrous dysplasia of craniofacial bones proved by surgery and pathology were examined with conventional X-ray. Of them, 4 cases were also studied with CT. The X-ray radiologieal findings of these ten patients were evaluated and compared with CT retrospectively. Results Of the 10 cases of FDB, 4 were of single bone type and 6 were of multiple bone type. The lesions were classified into dense, ground glass, cystic and mixed types according to their radiological manifestations. Of the 4 patients taking both the X- ray and CT examination, 1 case was coincided neighter in the location type of lesion, 2 were coincided in location but not in type of lesion, and 1 was not coincided neighter in the location nor in type of lesion. Evidently CT was more accurate and more valuable than ordinary X-ray. Conclusions Conventional X-ray could diagnose fibrous dysplasia of craniofacial bones, yet CT imaging has greater diagnostic value for the localization of multiple bone type FDB and more accurate classification of type of lesion because of its high resolution. Therefore CT is more conductive to distinguish it from ossifying fibroma.
