易误诊的子宫肌瘤超声图像特点及误诊原因分析

摘要

目的：分析超声诊断子宫肌瘤的准确性及容易被误诊的子宫肌瘤声像图特点及误诊原因。方法：分析759例子宫肌瘤中43例术前超声未能诊断子宫肌瘤的病例的声像图特征，术后对比其超声诊断与病理结果。结果：术前超声诊断子宫肌瘤正确率94.33％。43例误诊病例中，最常被误诊的疾病为子宫腺肌瘤，其次为卵巢肿瘤，少见的疾病有子宫肉瘤、残角子宫。结论：大多数子宫肌瘤具有典型的声像图表现，但当肌瘤体积较大或病理类型及位置特殊时易被误诊为其他疾病。超声检查时注意图像细节的观察及相关病史，有助于减少误诊。%Objective:To evaluate the diagnostic accuracy of ultrasonic images in uterine leiomyoma and to analyze the characteristic of misdiagnosed uterine leiomymoa and misdiagnose causes.Methods:43/759 cases diagnosed as uterine leiomyoma were compared in their pathologic results after operation and their ultrasonic images retrospectively .Results:The diagnostic accuracy of uterine leiomyoma was 94.3%.The common diseases misdiagnosed as uterine leiomyoma were uterine adenoma and ovarian tumor.The uncommon diseases were uterine sarcoma; rudimental uterine.Conclusion:Uterine leiomyoma has its own typical ultrasonic characters.Sometimes it will be diagnosed as other diseases for which have the similar images.It is necessary to observe ultrasonic images carefully and collect the patients history.
