Objective To investigate the imaging characteristics of endometrial polyps by using transvaginal ultrasound and analyze the causes of misdiagnosis. Methods Fifty-seven patients pathologically diagnosed of endometrial polyps were retrospectively analyzed. Results The endometrial polyps had its own characteristics of ultrasound images, especially the lesion, size, shape, echo, border, color Doppler flow imaging (CDFI) and so on. Conclusion Endometrial polyps has some special features on ultrasound image. Inspection in the secretary period, along with endometrial hyperplasia of the merger as well as multiple myoma the merger may result in misdiagnosis.
【摘要】 目的 探讨经阴道彩色多普勒超声诊断子宫内膜息肉的价值，进一步提高子宫内膜息肉的诊断准确率。 方法 2009年1月-2010年12月，对48例子宫内膜息肉患者，经阴道彩色多普勒超声发现病灶后观察其位置、大小、内部回声及病灶内部和周边的彩色血流情况，并与手术病理结果对照。 结果 经阴道彩色多普勒超声诊断子宫内膜息肉的准确率为87.5%， 2例误诊为子宫黏膜下肌瘤，3例误诊为子宫内膜增厚，1例漏诊。 结论 经阴道彩色多普勒超声对子宫内膜息肉有较高的临床诊断价值。【Abstract】 Objective To investigate the value of transvaginal color doppler ultrasonography in the diagnosis of endometrial polyps and to further improve the diagnostic accuracy. Methods From January 2009 to December 2010, fourty-eight patients with endometrial polyps participated in this study. Transvaginal color doppler ultrasonography was used to observe the location, size, and internal echo of the lesions, and the color flow within and around the lesions. Then, we compared all the ultrasonic features with pathological findings. Results The diagnostic accuracy of transvaginal color doppler ultrasonography in the diagnosis of endometrial polyps was 87.5%. Two cases were misdiagnosed as submucosal uterine fibroids, 3 as endometrial thickening, and 1 missed. Conclusion Transvaginal color doppler ultrasonography has a high clinical value in the diagnosis of endometrial polyps.
目的：评价宫腔声学造影(SHG)对子宫内膜息肉的诊断价值。方法：对临床拟诊宫内膜息肉的76例患者进行TVS、SHG及宫腔镜手术病理检查，并对结果进行分析。结果：以手术病理结果作为诊断金标准，内膜息肉48例，黏膜下肌瘤9例，内膜增生10例，宫腔内机化血凝块3例，正常内膜6例。SHG对子宫内膜息肉诊断的准确性为93.4%，敏感性为93.7%，特异性为92.8%。TVS对子宫内膜息肉诊断的准确性为59.2%，敏感性为81.2%，特异性为21.4%。两种方法对内膜息肉的诊断准确率比较有显著差异(χ2=5.45，P=0.019)。结论：宫腔声学造影准确率高，是诊断子宫内膜息肉的可靠方法。
