目的

探讨超声与磁共振成像在胎儿腹股沟斜疝诊断中的临床应用价值。

方法

对2003年2月至2015年2月在湖北省妇幼保健院产前超声检查的671 558例胎儿行系统超声检查,并对超声检出腹股沟斜疝和疑诊睾丸肿瘤的胎儿行磁共振成像(MRI)和出生后超声复查。与出生后临床、超声检查结果对照,对腹股沟斜疝胎儿的超声及磁共振图像特征进行分析。

结果

3例胎儿单纯性腹股沟斜疝均发生在晚孕期,临床罕见(发生率0.4/万,3/671 558),产前超声典型特征:(1)右侧阴囊增大,阴囊内见混合性肿块及蠕动的肠管回声。(2)单侧(左侧)睾丸可显示,阴茎可显示。磁共振成像示3例胎儿右侧腹股沟区腹壁连续性中断,疝囊内容物为肠管及网膜组织。出生后新生儿外科体检示3例男婴右侧阴囊大,疝入阴囊的包块可回纳,超声复查显示为腹股沟斜疝。与胎儿MRI及新生儿检查结果对照,产前超声正确诊断单纯性腹股沟斜疝2例,误诊为睾丸肿瘤1例;磁共振正确诊断单纯性腹股沟斜疝3例。

结论

胎儿单纯性腹股沟斜疝有特征性超声表现,超声及MRI联合检查有助于正确诊断而减少漏误诊。

Objective

To explore the clinical value of ultrasound and MRI in diagnosis of simple fetal indirect hernia.

Methods

A total of 671 558 fetuses were examined in maternal and child healthcare hospital of Hubei from February 2003 to February 2015. Once inguinal hernia or testicular tumors was suspected, MRI examination was performed after prenatal ultrasound. Final diagnosis was confirmed by postnatal follow-up. The ultrasonographic characteristics of fetal indirect hernia were compared with prenatal MR image characteristics and postnatal follow-up results.

Results

Three cases were confirmed after birth. The simple fetal indirect hernia was uncommon clinical entity which occurred during 3rd trimester. The ultrasonic characteristics in prenatal period were: (1) Right enlarged scrotum was filled with heterogeneous lesion; intestinal peristalsis within the scrotum was found in real-time ultrasonography. (2) The contralateral testis in left scrotum and penis could be found. MRI could display the characteristics of indirect hernia contents and its extension from abdominal cavity into inguinal region, which may help diagnose fetal simple indirect hernia. One case of fetal indirect hernia was misdiagnosed as testicular tumors, which was correctly diagnosed by MRI.

Conclusions

The simple fetal indirect hernia can be prenatally diagnosed by characteristic ultrasonic features, which can present with abnormal mass in inguinal region. Prenatal ultrasound is the primary screening method of fetal indirect hernia. MRI can serve as a supplement approach. The combination of US and MRI can further improve the diagnostic accuracy of fetal indirect hernia.
