摘　　要：目的探讨深部浸润型子宫内膜异位症的MRI表现特点。方法回顾性分析15例深部浸润型子宫内膜异位症患者的临床资料和MRI检查结果。结果深部浸润型子宫内膜异位症主要累及子宫骶骨韧带、阴道、子宫直肠凹、直肠,输尿管等亦可受累,其MRI主要表现为信号和结构紊乱、受累部位不规则增厚或结节形成、相邻组织和器官的变形牵拉,本研究中9例累及子宫骶骨韧带,12例累及阴道,3例位于子宫直肠凹,6例侵犯直肠,2例位于输尿管。结论对于深部浸润型子宫内膜异位症,MRI不但能准确定位,还能显示病变范围,是术前检查及术后随访的重要方法。Objective To explore the characteristics of deep infiltrating endometriosis on MRI（ magnetic resonance ima- ging）. Methods The clinical and MRI data of 15 patients with deep infiltrating endometriosis were retrospectively collect- ed and analyzed. Results On MRI, deep infiltrating endometriosis mainly affected uterosacral ligaments, vagina, pouch of Douglas, and rectum. Ureter was also involved sometimes. The main manifestations include the abnormalities of signal in- tensity and morphology, the deformation and tethering of surrounding organs and tissues as well as the irregular thickening of involved lesions or the formation of solid nodules. In this study, the uterosacral ligaments were involved in 9 cases, 12 cases infiltrated vagina,lesions of 3 cases were located in pouch of Douglas, rectum were invaded in 6 cases and ureter in- volvement was present in 2 cases. Conclusion MRI manifestations of deep infiltrating endometriosis can provide informa- tion of the anatomic locations and the lesion extension, which is an important method for examination before surgery and fol- low-up after surgery.
