长椭圆形

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 walls 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.
