摘要
目的:探讨骨硬纤维瘤的影像表现特征。方法:回顾性分析经病理证实的7例骨硬纤维瘤的临床及影像学资料。结果:7例骨硬纤维瘤均位于四肢管状骨,均为单发病灶,其中股骨3例、胫骨2例、腓骨1例、桡骨1例。位于干骺端5例、骨干2例。X线及CT表现为:中心性囊状膨胀性改变4例,偏心性囊状膨胀性改变3例,瘤壁见不同程度硬化,内见粗细不等的骨嵴,其中3例可见"根须"状肿瘤性骨小梁,均无钙化基质及骨膜反应。MRI表现:2例病灶T1WI呈等低信号,T2WI上病灶信号与周围肌肉相等或略低,其中可见小斑片状、条索状高信号,增强扫描见不均匀强化。结论:骨硬纤维瘤的影像学表现具有一定的特征,术前正确诊断有助于临床治疗及对预后的正确评估。
Objective To investigate the imaging features of bone desmoplastic fibroma. Methods The clinical and imaging data of 7 cases with pathologically confirmed bone desmoplastic fibroma were analyzed retrospectively. Results All the bone desmoplastic fibroma of 7 cases were located in the limbs bone, and all were single lesions, including 3 cases of femur, 2 cases of tibia, 1 case of fibula, and 1 case of radial bone. Five cases located in the metaphysis, and 2 cases in the backbone. The results of X-ray and CT were as follows： 4 cases were of central cystic expansion change, 3 cases were of eccentric cystic expansion change, the wall of tumors was seen to have different levels of hardening, with bone ridge of different thickness, of which 3 cases were of ＂Roots ＂ like tumor bone trabecula, without any matrix calcification and periosteal reaction. The performance of MRI was as follow： 2 patients showed low-signal lesions in TIWI, the lesion signal equaled to or slightly was lower with the surrounding muscle in TzWI , of which small patchy or cord-like high signal could be shown, and the heterogeneous enhancement could be seen for the enhanced scan. The imaging of bone desmoplastic fibroma has certain characteristics, so correct preoperative clinical diagnosis will be helpful for the clinical diagnosis and the correct assessment of prognosis.
