摘　　要：目的探讨磁共振成像(MRI)诊断半月板易误诊为撕裂的影响因素。方法回顾性分析16例经手术或关节镜检查确诊为非半月板撕裂患者的临床及MRI资料。结果 16例患者半月板均无撕裂,其中8例为板股韧带与外侧半月板后角的高信号移行部(5例高信号平行于后缘,呈纵形;3例呈斜形,分别位于后角后上缘及后下缘);4例为膝横韧带与内侧半月板前角的高信号结合部(2例结合部在半月板前角前上缘,1例在后上缘,1例在前角根部);1例为前交叉韧带与外侧半月板前角的高信号附着部;1例为外侧半月板后角的魔角效应;1例为半月板挫伤;1例为半月板撕裂术后的愈合瘢痕。结论诊断半月板撕裂要密切结合临床病史、患者检查体位、半月板自身及周围结构等诸多因素综合考虑,才能作出较为准确的诊断。Objective To investigate the factors affecting the diagnosis of MRI in the tear of the meniscus.Methods The clinical and MRI data of 16 cases with non meniscus tear were retrospectively analyzed. Results Sixteen patients had no tears, and 8 cases had high signal moving part of the posterior horn of the lateral meniscus（5 cases with high signal parallel to the trailing edge, longitudinal shape; 3 cases were in the shape of the oblique, which were located in the posterior margin of the posterior margin of the upper and lower margin）; 4 cases of high signal were the medial meniscus joint part of the transverse geniculate ligament and the anterior horn（2 cases were in the anterior part of the anterior horn of the meniscus, 1 case was in the back, 1 case was in the anterior horn root）;1 case had high signal attachment of anterior cruciate ligament and anterior horn of lateral meniscus;1 case had magic angle effect of posterior horn of the lateral meniscus; 1 case was meniscus contusion; and 1 case was postoperative scar healing of the meniscus tear. Conclusion Diagnosis of meniscus tear should be closely combined with the clinical history, the patient′s examination position, the body and the surrounding structure and so on, which can make more accurate diagnosis.
