ABSTRACT
Objective To summarize the ultrasonographic features and differential diagnosis of uterine cornual pregnancy.Methods Trans-abdominal and trans-vaginal ultrasound were performed in 93 uterine cornual pregnancy patients before surgery,ultrasonographic findings of uterine cornual pregnancy through different two approaches were analyzed and compared with surgical and pathologic findings.ResultsIn contrast with surgical and pathological diagnosis,66 cases(82.5%,66/80) of uterine cornual pregnancy were accurately diagnosed by ultrasonography before surgery,these cases were divided into gestational sac pattern (55 cases) and mixed mass pattern(11 cases); 11 cases were misdiagnosed as interstitial tubal pregnancy,2 cases were misdiagnosed as pregnancy in rudimentary horn,1 case was misdiagnosed as choriocarcinoma,misdiagnosed rate were 17.5%(14/80); uterine cornual pregnancy presented as adnexal mass in ultrasound in 13 cases,while ruptured uterine cornual mass were found in surgery,in which location and type of the masses couldn't be accurately diagnosed by ultrasound.Ultrasonographic features of uterine cornual pregnancy presented as a gestational sac located in extended cornual of uterus,surrounded by thin myometrium,and connected with endometrium.The misdiagnosed causes were (1) Uterine cornual mass was not connected with endometrium or surrounded by thin myometrium,which were misdiagnosed as interstitial tubal pregnancy.(2) Uterine cornual pregnancy with thick lateral myometrium were misdiagnosed as pregnancy in rudimentary horn.(3)Uterine cornual pregnancy presented as cornual mass with abundant blood flow was misdiagnosed as choriocarcinoma.Conclusions Uterine cornual pregnancy can be accurately diagnosed by trans-abdominal and trans-vaginal ultrasound.Ultrasonographic features are helpful in differential diagnosis of uterine cornual pregnancy.
