摘要
目的：探讨膝关节半月板囊肿的MRI表现与诊断价值。方法：经关节镜手术病理证实的膝关节半月板囊肿患者23例,其中男性16例、女性7例;年龄22~59岁,平均43岁。术前经MRI检查,治疗采用关节镜手术,并作病例组织诊断,回顾性分析其MRI影像与关节镜检查结果。结果：23例半月板囊肿患者中,内侧半月板囊肿6例（26.09%）,外侧半月板囊肿17例（73.91%）,MRI诊断与关节镜检查结果相一致。伴有半月板水平撕裂15例（65.22%）,纵行撕裂3例（15.05%）。内型半月板囊肿呈硬币样类圆形或类三角形长T2信号,位于半月板内,与半月板分布一致;半月板旁型囊肿位于半月板周围,呈类圆形或卵圆形长T1T2信号,边缘清楚。结论：MRI对膝关节半月板囊肿的诊断具有重要临床价值,可为临床治疗方案提供可靠的依据。
Objective To discuss MRI features of meniscus cyst in the knee joint and their diagnostic values. Methods To- tally 23 meniscus cyst patients confirmed by arthoscopy underwent preoperative MRI examination, who involved in 16 males and 7 females, and aged from 22 to 59 years old and had the mean age of 43 years old. The MRI features and arthoscopy results were analyzed retrospectively. Results MRI and arthoscopy both found there were 6 ones （26.09%） with the cyst in the medial meniscus and 17 ones （73.91%） in the lateral meniscus, and there were 15 ones （65.22%） with meniscus hori- zontal tear and 3 ones with longitudinal tear. The medial meniscus cyst in the meniscus had MRI features of circular or tri- angular long T2WI. The para-articular meniscus cyst around the meniscus had the MRI features of circular or orbicular long TIT2, with clear margin. Conclusion MRI is of great value for the diagnosis of meniscus cyst, and can provide references for clinical treatment.
