摘　　要：目的探讨CT、MRI在股骨颈疝窝中的诊断及鉴别诊断价值。方法回顾性分析徐州市中医院及丰县人民医院2014年6月—2016年12月诊治的50例股骨颈疝窝的临床及影像学资料。42例患者行16或64排CT检查,8例行MRI检查。结果 50例患者共55个疝窝病灶,其中双侧5例,右侧24例,左侧21例。病灶位置:均位于股骨头颈结合部前外侧皮质下(n=34);病灶形态:圆形19个、椭圆形23个,"8"字形13个;病灶大小:3.2 mm×3.0 mm^13.5 mm×11.0 mm,平均(8.52±0.65)mm。MSCT上病灶呈界限清晰,周边伴薄层硬化环的低密度影。MRI上病灶呈T1WI低或中高信号,T2WI及脂肪抑制序列高信号影。43个病灶可见裂隙向外穿越邻近骨皮质。结论股骨颈疝窝具有特定的发病部位及的影像学表现,CT及MRI可对本症作出诊断及鉴别诊断。Objective To study the application value of MSCT and MRI in diagnosis of herniation pit of femoral neck.Methods 50 cases of patients with herniation pit of femoral neck diagnosed in our hospital from June 2014 to December2016 were selected including 42 cases undergoing the 16 or 64 spiral CT examination and 8 cases undergoing MRI examination. Results There were 50 hernia lesions of 50 cases, including 5 bilateral cases, 24 right cases and 21 left cases, and the lesion site was in the anterolateral subcortical femoral head neck joint lesion(n=34), and the lesion shape: 19 were circular, 23 were oval, 13 were '8' glyph; lesion size: 3.2 mm×3.0~13.5 mm×11.0 mm,(8.52±0.65)mm on average, and the boundary of lesions in MSCT was clear with low density shadow, and the lesions on MRI showed a T1 WI low or middle or high signal, and gas outward through cortical bone was in 43 lesions. Conclusion The herniation pit of femoral neck has the specific disease position and imaging manifestations, and CT and MRI can make diagnosis and differential diagnosis of the disease.
