摘要
目的:探讨先天性阴道畸形及处女膜闭锁的MRI及超声影像表现,分析其特点,提高对该病的认识。方法:12例经临床证实的先天性阴道畸形和处女膜闭锁病例,对其MRI、超声影像资料进行回顾性分析,分别计算准确率,应用卡方检验统计两者准确率差异性。结果:先天性阴道畸形(7例),为副中肾管发育畸形,先天性无阴道畸形伴痕迹子宫或无子宫2例,为Mayer-Rokitansky-Kstner-Hauser(MRKH)综合征;阴道斜隔综和征2例,超声误诊1例;阴道闭锁2例,其中1例为宫颈发育不良伴阴道闭锁;阴道横隔1例;处女膜闭锁5例。MRI诊断准确率为100%(12/12),超声诊断准确率为83.3%(10/12),两者统计学无明显差异(P>0.05),但MRI检查较超声准确率高。结论:先天性阴道畸形和处女膜闭锁的MRI及超声影像表现有一定特征,超声可作为首选的筛查检查方法,进一步MRI检查可以提高诊断准确率。
Objective：To approach magnetic resonance imaging（MRI）and US manifestation of congenital vagina abnormal and imperforate hymen,analysis characteristics.Methods：To analyze retrospectively MR and US manifestation of 12 female patients confirmed,we compared the differences of accuracy.On statistics,χ2-test was used.Results：Vagina abnormal（n=7）is Müllerian duct development malformation.congenital vagina abnormal or absence of uterus（n=2）,i.e.Mayer-Rokitansky-Küster-Hauser（MRKH）syndrome;Vagina oblique septum（n=2）,one case misdiagnosis by US;vagina atresia（n=2）,one case with cervix dysplasia;vagina transverse septum（n=1）;congenital imperforate hymen（n=5）.Accuracy of MRI is 100%,US is 83.3%.statistically it was considered unsignificant（P0.05）,but accuracy of MRI is higher than US.Conclusion：MR and US manifestation of congenital vagina abnormal and atresia hymenalis have characteristics,US can to be first choice for screening and MRI can improve accuracy of diognosis.
