摘　　要：目的：探讨盆腔部卵巢外部位的子宫内膜异位症的 MRI 表现及特点。方法回顾性分析经手术病理证实的13例盆腔部包括腹壁卵巢部位外的子宫内膜异位症的临床资料和 MRI 影像表现。常规采取 MRI 平扫、T1 WI、T2 WI 脂肪抑制及 T1 WI 增强的矢状、横断扫描。重点分析盆腔深部及腹壁部位异常影像灶分布及 MRI 信号征象，并结合其临床表现。结果13例异位病灶，直肠子宫凹4例，膀胱壁2例，单侧输尿管膀胱入口2例，肛管壁1例，腹壁4例，其中实性病灶10个（10/13），囊实性3个（3/13）， MRI 信号表现呈多样性。结论盆腔卵巢外部位子宫内膜异位病灶呈实质性或囊实性，分布于盆腔深部子宫周围泌尿系脏器及间隙、直肠壁及其间隙内和下腹壁手术切口处。MRI 有助于异位病灶的检出，诊断尚需密切结合临床病史。Objective To explore the MRI features of pelvic endometriosis outside the ovary.Methods 13 patients with pelvic endometriosis outside the ovary were imaged.Their clinical and imaging data were reviewed retrospectively.All cases were con-firmed by pathology.An enhanced MR using T1 WI sequence both in sagittal and transverse position was performed after T2 WI fat-suppression sequence and T1 WI sequence.Our MRI study was focused on the distribution of lesions locating in the deep pelvic cavity and abdominal wall,and the features of MRI signals .Results 13 lesions were found,in which 4 lesions located in the rectouterine pouch of Douglas,2 cases the bladder wall,2 cases the unilateral cystic inlet of ureter,1 case the anal canal wall,and 4 cases the ab-dominal wall.10（10/13）lesions were shown as solid nodules while 3（3/13）lesions as cyst-solid ones.All lesions showed moderate-ly heterogeneous enhancement.Conclusion Pelvic endometriosis outside the ovary mainly shows solid or cyst-solid lesions that lo-cates in the urinary,uterus,rectal wall and spaces around them.MR images show a higher value for the detection of the lesions out-side the ovary.
