摘　　要：目的 :探讨股骨近段囊型骨纤的诊断与鉴别诊断。方法 :回顾性分析 1 5例经手术病理证实的股骨近段囊型骨纤的影像学表现 ,所有病例均有X线平片 ,1 0例行CT扫描 ,2例行MR检查。结果 :病变位于股骨颈 7例 ,转子间 5例和转子下 3例。形态为椭圆形 8例 ,圆形或类圆形 3例 ,呈偏心的半圆形 4例。病变均有硬化缘 ,其内密度不均匀 1 3例(86 6 % ) ,9例呈半透明的或浓密的毛玻璃样密度 ,5例为囊状透光灶 ,8例在病变区内见到絮状略高密度影 (53 % ) ,3例在毛玻璃密度中有小囊状低密度灶 ,1例有斑点状钙化。结论 :股骨近段囊型骨纤形态多样 ,病变伴有清楚的硬化缘 。Objective:To study the imaging and differential diagnosis of cystoid fibrous dysplasia of the proximal part of the femur.Methods:[ WT5”BZ]15 cases were proved surgically and pathologically.All 15 cases with plain film,10 cases with CT and 2 cases with MRI were retrospectively analyzed.Results:[WT 5”BZ]Lesions located in the n eck of femor in 7 cases,intertrochanter in 5 cases and subtrochanter in 3 cases. 8 lesions were oval,3 lesions were round or roundlike and 4 lesions were eccente r semi-circular.AII lesions had sclerotic rim. 13 lesions were heterogeneous,9 lesions had translucent or thick ground glass density.5 lesions were cystic tran sparent,8 lesions can be seen floculent sightly high density opaque,3 lesions ca n be seen small cystic low density opaque in the ground glass ones and 1 lesion had spotted calcification.Conclusion:Cystoid f ibrous dysplasia of the proximal part of the femur was variform,with a very dens e encapsulated rind of scelerosis and that the lesion contained ground glass an d wadding ossifing opaque was its characteristic.
