We report a case of body stalk anomaly detected prenatally by fetal magnetic resonance imaging (MRI) at 14 weeks' gestation. A 29-year-old woman was followed during her first pregnancy. At 11-12 weeks' gestation, our sonographic images showed multiple fetal deformities. An abdominal wall defect was suspected. The exteriorized abdominal contents and the lower limb appeared within the extraembryonic celom with an intact amniotic membrane. Fetal MRI at 14 weeks' gestation confirmed a large anterior wall defect with herniation of the liver and bowel. In addition, abnormally rotated lower limb and scoliosis could be demonstrated. The fetus was prenatally diagnosed with body stalk anomaly, expected to be lethal in nature. The parents decided to terminate the pregnancy at 15 weeks' gestation. Prenatal diagnosis of body stalk anomaly is usually based on sonographic findings. As far as we are aware, this is the first case report of body stalk anomaly satisfactorily diagnosed by fetal MRI in the early second trimester. Fetal MRI scans should provide ground for a precise antenatal diagnosis of body stalk anomaly from early gestation.
我们报告了一例 14 孕周胎儿磁共振成像（MRI）产前检测到的体干异常。一位 29 岁的女性在首次妊娠期间接受了随访。在 11-12 孕周，我们的超声图像显示了多种胎儿畸形。怀疑存在腹壁缺损。腹外内容物和下肢在羊膜外胚外腔中显现，羊膜完整。14 孕周的胎儿 MRI 证实了一个大的前壁缺损，肝脏和肠管疝出。此外，还可以显示出异常旋转的下肢和脊柱侧凸。胎儿被产前诊断为体干异常，预计具有致命性。父母决定在 15 孕周终止妊娠。体干异常的产前诊断通常基于超声检查结果。据我们所知，这是首例在孕中期早期通过胎儿 MRI 满意诊断的体干异常病例报告。胎儿 MRI 扫描应为早期妊娠的体干异常提供精确的产前诊断依据。
