目的：探讨胎儿并腿畸形的骨骼异常及尸检胎儿 MSCT容积再现对产前B超的提示作用。方法：对8例疑似并腿畸形胎儿行 MRI检查，引产后行 MSCT检查。结果：8例并腿畸形胎儿中，7例为单胎，1例为臀部联体双胎之一。8例中，1例表现为单个下肢，7例为形式各异的下肢融合畸形。8例均有髂骨异常、尾椎部分或全部缺失。7例伴有各种各样的胸腰椎和肋骨畸形，2例并左上肢畸形融合。结论：MSCT容积再现可以提供胎儿详细立体的影像学资料，提高对并腿畸形骨骼异常的认识及产前诊断水平。

Objective:To discuss the skeletal anomalies of sirenomelia of fetus and the value of post-natal MSCT with volume rendering technique for fetal prenatal ultrasound.Methods:8 fetuses suspected of sirenomelia underwent MRI exami-nation and these fetuses after induced labor underwent MSCT examination.Results:Of the 8 cases of sirenomelia,7 cases were monocyesis,and one case was one of coxal conjoined twins,one of the twins had sirenomelia.Of the 8 cases,one case had single lower limb,7 cases had various fusion of the lower limbs.There were iliac bone anomalies and complete or partial caudal vertebra defects in 7 cases.There were various deformities of thoracic and lumbar vertebrae and ribs deformities in 7 cases and fusion of the upper limbs in 2 cases.Conclusion:MSCT with volume rendering can provide significant and clear im-aging information of the entire fetus,which can improve the understanding and prenatal diagnostic level of skeletal anomalies of sirenomelia.
