摘　　要：目的探讨MRI对阑尾粘液囊肿的诊断价值。方法搜集3例经手术及病理证实的阑尾粘液囊肿临床及MRI资料,分析其MRI表现。结果3例病变均位于右下腹,冠状面位于髂肌和腰大肌形成的“V”形间隙内,与盲肠关系密切,盲肠呈外压改变;呈均匀长T1、长T2信号;壁薄且均匀,信号与肠管壁相似,于T2WI显示较明显;于横断面分别呈圆形、类圆形及椭圆形,冠状面及矢状面2例显示呈“葫芦”状、1例呈长管状,3例末端均呈“桃尖”样变;边界均清楚。1例于阑尾开口部发生盲肠息肉,MRI未能显示。结论阑尾粘液囊肿的MRI表现有一定特征性。Objective To study the diagnostic value of the MRI image in appendical mucous cyst. Methods The clinical data and MRI image were collected from 3 cases with appendical mucous cyst confirmed by operation and pathology, and the findings of MRI were analyzed. Results 3 cases of lesions were in the gap of ＂V＂ shape between iliac muscle and musculus psoas major on the coronal sections in the lower right abdomen closely adjacent to the cecum, which were narrowed. The lesions showed long even T1 and T2 signals similar to mucous wall particularly in T2WI image. The wails of cyst were thin and even. The cysts were round or oval in shape on transections. The cyst were cucurbits in shape in 2 cases and long cannular in a case on coronal sections and arrowy sections and borderlines of the cysts were clear, The terminal of the cysts showed taper in 2 cases. In addition, cecum polypus was found at the placket of the appendix in a case which was not shown on MRI image. Conclusion MRI images of appendical mucous cyst are characteristic.
