目的分析股骨颈疝窝的影像表现.方法回顾性分析9例股骨颈疝窝的X线平片、CT和MRI表现.9例均为男性,年龄21-73岁,均有髋部疼痛,疼痛史2个月至2年.结果 9例中6例股骨颈疝窝为双侧,3例为单侧(右),其中行X线平片检查2例,CT 6例,MRI 5例.疝窝大小为0.5 cm×0.6 cm～1.0 cm×1.5 cm.位于股骨颈前上区(7例)或前下区(2例).X线平片示股骨颈区囊状低密度区,围以硬化白边.CT示股骨颈皮质下低密度区,有硬化边缘,其中2例有骨皮质细微断裂.5例MR T1WI呈低信号,其中3例T2WI呈高信号,围以低信号带,2例呈低信号,脂肪抑制序列5例均呈高信号,矢状面示疝窝位于髂腰肌背侧.T2WI示髋关节少量渗液2例.结论股骨颈疝窝具有特征性的CT、MRI表现,CT、MRI有利于明确股骨颈疝窝的诊断.

Objeetive To evaluate imaging appearances of herniation pit of the femoral neck.Methods We retrospectively analyzed the X-ray,CT and MRI findings of 9 patients with herniation pit of the femoral neck.All nine patients were male with the age ranging from 21 to 73 years.They had pain in the hip from two months to two years duration.Results The bilateral hips were affected in six patients,the right hips in the other 3 patients.Of the nine patients,X-ray plain films(2 cases),CT scanning(6 cases),and MR scanning(5 cases)were performed.The size of the lesions ranged from 0.5 cm×0.6 cm to 1.0 cm×1.5 cm,located in the anterosuperior portion of the femoral neck(n=7)or anteroinferior portion(n=2).X-ray plain films showed an osteolytic lesion surrounded by a sclerotic rim.CT scanning showed the lesion just below the cortex of the femoral neck surrounded by a rim of sclerosis or associated with a small cortical break in two patients.MR scanning showed low signal intensity in five patients on T1WI and high signal intensity surrounded by a rim of low signal intensity(n=3)or low signal intensity(n=2)on T2WI,and high signal intensity on fat suppression MR image.A small joint effusion was observed in two cases on T2WI.Conclusion The CT and MRI findings of herniation pit of the femoral neck are characteristic,it is useful in defining the diagnosis of the herniation pit of the femoral neck.
