颅面部骨纤维异常增殖症DR及MSCT影像学表现分析

DR and MSCT Imaging Features of Craniofacial Fibrous Dysplasia of Bone

目的分析颅面部骨纤维异常增殖症DR及MSCT影像学表现。方法回顾分析本院2017年6月至2019年7月收治的67例颅面部FDB患者作为研究对象,所有患者均进行DR及MSCT检查。对患者所得DR及MSCT图像进行分析,并对比两种检查对颅面部FDB检出率。结果MSCT对颅面部FDB检出率为98.50%,稍高于DR检查(95.52%),但两者比较无明显差异(P>0.05);67例颅面部FDB患者中,71.64%(48/67)患者为多骨型,其余28.35%(19/67)为单骨型,无Albright综合征患者。DR图像表现:患者外板、板障骨质出现膨大、增厚,颜面骨有局限性或者呈广泛性增大。67例患者中43例为磨玻璃样改变,囊状样改变16例,弥漫性硬化改变5例,“丝瓜瓤”样改变3例。MSCT图像表现:患者病变处骨正常结构消失,且有不同程度膨性增粗、畸形,检查中无软组织肿块影出现。结论颅面部FDB患者在DR、MSCT检查中影像学特征明显,DR检查可反映出整体病灶情况,而MSCT检查对病灶内部解构、范围、复杂部位显示等方面显示有优势,可作为首选检查方法。

Objective To analyze the DR and MSCT imaging features of craniofacial fibrous dysplasia of bone.Methods 67 patients with craniofacial FDB treated in our hospital from June 2017 to July 2019 were retrospectively analyzed.All patients underwent DR and MSCT examinations.The DR and MSCT images of the patients were analyzed.Results The detection rates of craniofacial FDB between the two examinations were compared.The detection rate of craniofacial FDB by MSCT was 98.50%,which was slightly higher than that by DR(95.52%),but there was no significant difference between the them(P>0.05).In the 67 patients with craniofacial FDB studied in this article,71.64%(48/67)patients were bony,and the remaining 28.35%(19/67)were single-bone.There were no patients with Albright syndrome.The DR image showed that the outer plate and diploe bone of patients was enlarged and thickened.Facial bones have limitations or were extensively enlarged.In the 67 patients,43 patients had ground glass-like changes,16 patients had cystic changes,5 patients had changes of diffuse sclerosis,and 3 patients had"vegetable sponge"-like changes.The MSCT image showed that the normal bone structure of the patient's lesion disappeared.There were different degrees of swelling,thickening and deformity.No soft tissue masses shadow appeared in the examination.Conclusion In DR and MSCT examinations,the imaging features of patients with craniofacial FDB were obvious.DR examination can reflect the situation of overall lesion,while MSCT examination has the advantages in display of the internal structure,scope,and complex parts of the lesion,which can be used as the preferred method of examination.
