摘　　要：目的探讨腹壁子宫内膜异位症的磁共振成像(magnetic resonance imaging,MRI)表现特点。方法回顾性分析北京协和医院2008年1月至2013年1月经手术病理证实且行MRI检查的7例腹壁子宫内膜异位症患者的临床资料和MRI检查结果。结果 7例腹壁子宫内膜异位症患者中5例单发,2例多发;7例患者共发现病灶10处,7处病灶位于左侧,2处位于正中,1处位于右侧;5处位于皮下及筋膜、未侵及腹壁肌层,4处侵及腹壁肌层,1处累及皮下、筋膜及腹壁肌层;2处病灶与盆腔内部脏器粘连。10处病灶中,9处病灶呈实性,T1WI及T2WI上以等信号或稍高信号为主;1处病灶呈囊性,T1WI呈高信号,T2WI可见"阴影"现象。7例患者有5例合并子宫疾病。结论对于腹壁子宫内膜异位症,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 abdominal wall endometriosis （AWE） on magnetic resonance imaging （MRI）.Methods The clinical and MRI data of 7 patients with pathologically confirmed AWE in Peking Union Medical College Hospital from January 2008 to January 2013 were retrospectively collected and ana-lyzed.Results Five of the AWE lesions were single and two were multifocal .Ten AWE lesions were found in 7 patients .Seven out of 10 lesions were located in the left , two in the middle , and one in the right .Five lesions were located in the subcutaneous tissue and fascia , the abdominal muscles were invaded in four lesions , and one was lo-cated in the subcutaneous tissue , fascia, and muscle.Endometrial invasion from the scar into the abdominal cavity was observed in two patients , with anterior wall and fundus of the uterus for one patient and anterior wall of bladder for another.Nine lesions were solid and mainly showed isointense or hyperintense signal on T 1WI and T2WI com-pared with muscle with foci of higher intensity on T 2WI.In one patient , a cystic hyperintense lesion was found on T1WI （including shading on T2WI）.Coexistent abnormality was observed in five patients , including adenomyosis in two, uterine malformation in one, adenomyosis and uterine malformation in one , and fibroid in one patient. Conclusions MRI manifestations of AWE can provide information on the anatomic locations and the lesion exten-sion.Thus, MRI is an important method for preoperative examination and postoperative follow -up.
