摘　　要：目的:探讨坐骨结节囊肿的MRI表现及MRI扫描的诊断价值。方法:回顾性分析12例经手术及病理证实的坐骨结节囊肿的MRI表现,其中3例进行了增强检查。结果:10例发生于单侧,2例发生于双侧。MRI平扫显示坐骨结节与臀大肌之间的间隙内可见长T1长T2信号灶,部分信号欠均匀,其中3例可见线状分隔,边界欠清,增强显示囊壁呈不规则强化,厚薄不均,肿块内无明显强化。结论:坐骨结节囊肿的MRI表现特征性较明显,其临床意义及诊断价值较高。Objective:o investigate the MRI manifestation of ischial tuberosity cyst and the diagnostic value of MRI scan.Methods:By retrospectively analyzing MRI manifestation of cyst in 12 cases of ischial tuberosity confirmed by surgery and pathology,of which 3 cases were with enhanced examination.Results:10 cases occurred on one side and 2 cases occurred on both sides.MRI plain scan showed a long T1 long T2 signal in the gap between the ischial tuberosity and the gluteus maximus,and some of the signals were not uniform.3 of them were linearly separated.The boundary was unclear and the enhanced display showed irregular enhancement of the wall.The thickness is uneven,and there is no obvious strengthening in the mass.Conclusions:The MRI features of ischial tuberosity cysts are more obvious,and their clinical significance and diagnostic value are high.
