子宫内膜异位症(Em) 超声检查在诊断Em方面的价值,文献报告不一。尽管最终诊断均必须经腹腔镜检查证实,但阴道超声(TVS)可强烈支持临床对Em的怀疑。在TVS上,典型的卵巢“巧克力囊肿”表现为无回声具有半固体实质性结构的囊肿,与胎儿的肝脏、胎盘或肺组织相似。囊肿可为均质或部分实质部分囊性,可单发或多发,单侧或双侧。有时与其它出血性卵巢囊肿(如黄体囊肿)难以分辨,但经过数周或1～3月的追踪随访,出血性卵巢囊肿内由于纤溶现象引起囊性成分与固体成分的比例改变,其显象也会有改变,而子宫内膜异位瘤和“巧克力囊肿”的质地通常不变。运用这一规律,10例有内膜异位
Endometriosis (Em) ultrasound in the diagnosis of Em value, the literature reports vary. Although the final diagnosis must be confirmed by laparoscopy, vaginal ultrasound (TVS) strongly supports the clinical suspicion of Em. On TVS, a typical ovarian “chocolate cyst” appears as a cyst with a semi-solid, non-echogenic structure similar to that of the fetus’s liver, placenta or lung. Cysts can be homogeneous or partially substantive cystic, can be single or multiple, unilateral or bilateral. Sometimes with other hemorrhagic ovarian cysts (such as corpus luteum cyst) difficult to distinguish, but after a few weeks or 1 to 3 months of follow-up, hemorrhagic ovarian cyst due to fibrinolysis caused by changes in the ratio of cystic and solid components, the significant Elephants may change as well, while the texture of endometriosis and “chocolate cyst” usually remains the same. Use this rule, 10 cases of endometriosis
