腹壁子宫内膜异位症的超声特征分析

Sonographic features analysis of abdominal wall endometriosis

目的回顾性分析腹壁子宫内膜异位症（AWE）的声像图特征和临床表现。方法行腹壁肿物切除术且术后病理证实为AWE的105例患者共119个病灶为研究对象，分别评价每个病灶的声像图特征。将病灶按最大直径分为〈3cm组和≥3cm组，比较两组声像图特征的差异。结果AWE的声像图特征为形态不规则的低回声，边界不清晰，内可有小的无回声区，周边可有强回声晕，彩色多普勒常表现为外周及内部少许血流信号。与≥3cm组病灶相比，〈3cm组病灶潜伏期较短，位置较浅，多位于皮下脂肪或浅肌层，病灶呈圆形或卵圆形，周边强回声晕，无或少许血流信号更为常见；≥3cm组病灶则潜伏期较长，呈不规则形，位置较深，丰富血流信号更为常见。结论使用高频灰阶及彩色多普勒超声，根据超声特征结合病史可对AWE作出定性诊断，并可判断病灶大小、范围及浸润深度，可为术前提供更多信息。

Objective To describe the sonographic features of abdominal wall endometriosis（AWE）. Methods 105 consecutive women with proven pathological endometriosis of the abdominal wall were retrospectively recruited. The clinical data and the result of the sonographie examinations were reviewed and described. The AWE lesions were divided into 〈~3 cm and ~3 cm groups according to their maximum diameter. Results The sonographic feature of AWE includes irregular hypoechoic nodules with ill-defined margins,anechoic and hyperechoic ring maybe exist. In color Doppler, most of them showed few internal vascularity. Compared with^3 cm group,~3 cm group nodules manifested as shorter latent period, with more superficial location,round or oval shape,peripheral hyperechoic ring and none or few vascularity were more common. As for ~3 cm group nodules manifested as longer latent period, with deeper location, irregular shape,abundant of vascularity were more common. Conclusions Specific diagnosis of AWE can be made by using high frequency sonography combined with clinical features. More accurate information can be provided by judging the size, range and infiltrative depth.
