摘要(Abstract):

目的:探讨臀肌挛缩症的X线、CT征象。方法:分析24例臀肌挛缩症的骨盆平片及其中11例骨盆CT片,并与21例非臀肌挛缩症的骨盆平片及其中8例CT片做对照。结果:24例臀肌挛缩症骨盆平片中,22例(91.7%)表现为双侧骶髂关节旁纵行、条状致密线,2例(8.3%)表现为单侧骶髂关节旁纵行、条状致密线;11例骨盆CT主要表现为:(1)臀肌体积缩小,10例(90.9%)为双侧,1例(9.1%)为单侧;(2)髂骨走形方向改变呈矢状,10例(90.9%)为双侧,1例(9.1%)为单侧;(3)臀部注射区臀肌钙化灶及条状挛缩带。结论:骶髂关节旁线状致密影是臀肌挛缩症的重要X线表现,CT能更直观地了解病变的范围及髂骨骨质改变,对临床早期诊断及术前评估具有重要意义。
Objective: To investigate the X-ray,CT signs and clinical manifestation of gluteal muscle contracture( GMC). Methods: Pelvic radiograph of 24 GMC cases including CT radiograph of 11 GMC cases were analyzed and compared with pelvic radiograph of 21 non-GMC cases and CT radiograph of 8 non-GMC cases among them. Results: Longitudinal dense linear shadows were found at the iliac site of sacroiliac joint in 24 cases with GMC,of whom 22( 91. 7%) cases were bilateral and 2( 8. 3%) cases were unilateral. The main CT signs in 11 cases with GMC were as follow:( 1) Gluteal muscle volume shrunk,10( 90. 9%) cases were bilateral and 1( 9. 1%) cases were unilateral.( 2)The normal direction of ilium were changed to sagittal direction,10( 90. 9%) cases were bilateral and1( 9. 1%) cases were unilateral.( 3) Gluteal calcification and strip erispation fascia occurred in injection zones. Conclusion: The longitudinal dense linear shadows is very important X-ray imaging features of GMC. CT can intuitively evaluate the extent of GMC and the change of ilium,which is useful for the early diagnosis and preoperative evaluation.
