摘　　要：目的探讨CT和MR I在股骨颈疝窝的影像学表现及诊断价值。方法回顾性分析总结经临床影像学诊断的10例股骨颈疝窝的影像学表现,所有病例均行X线平片和CT检查,其中2例行MR I检查。结果10例股骨颈疝窝均为单侧单发病灶,10例病灶中X线平片仅显示8例,表现为股骨颈外上侧的类圆形透亮区或硬化环。CT上表现为股骨颈前方皮质下的类圆形骨质缺损区,内为密度均匀的软组织密度,边缘清楚伴有硬化缘。MR I上表现为均匀长T1和长T2液体信号,灶周骨髓信号无异常。结论X线平片对股骨颈疝窝具有初步诊断价值,CT具有确诊价值,MR I具有辅助诊断价值。Objective To study imaging features and diagnostic value in herniation pit of femoral neck . Methods Imaging findings of 10 patients with herniation pits of femoral neck diagnosed by clinical imaging were retrospectively analyzed. All cases were examined by radiography and CT, and 2 cases by M RI. Results 10 herniation pits of the femoral neck were solitary lesions on CT t while only 8 lesions were displayed on X - ray film. On X - ray film t 8 lesions showed a round radiolucency with a thin clear sclerotic rim or simple sclerotic loop. On CT images , there were round defects under anterior cortical bone of the femoral neck which showed a well - defined lesion of fluid attenuation surrounded by thin clear sclerotic rim. On MRI images;2 lesions showed uniformly long T1 and long T2 fluid signal intensity. Conclusion In herniation pit of femoral neck, X -ray film is a good choice for primary diagnosis, CT scaning can make accurate diagnosis and MRI scaning is helpful to diagnosis.
