卵巢皮样囊肿的典型超声图像被描述为回声增强(increased echogenicity),在回声后常可见明显声影(acoustic shadowing)。Guttman报告20例,确诊率为85%,其他作者报告为50～60%,有的认为只有少数有典型表现。由于对皮样囊肿超声像表现和确诊率各文献差异较大,本文对已经外科手术切除病理证实的51例皮样囊肿病人的超声图像和23例X光平片进行回顾性研究分析。某医院三年内收治卵巢皮样囊肿病人51例,年 A typical ultrasound image of an ovarian dermoid cyst is described as increased echogenicity, often followed by acoustic shadowing. Guttman reported 20 cases, the diagnosis rate was 85%, other authors reported 50 to 60%, while others think that only a few have a typical performance. Because of the large differences in the ultrasound imaging and diagnosis rate of dermoid cysts, we retrospectively analyzed the ultrasound images of 51 cases of dermoid cysts confirmed by surgical resection and 23 cases of X-ray films. A hospital within three years admitted to ovarian dermoid cyst 51 patients, year
