The prenatal diagnosis of a human tail was suggested in six fetuses with ultrasound findings of an echogenic protrusion in the lumbo-sacral region. All fetuses were at 14-16 weeks' gestation. The ultrasound findings disappeared in all cases at 22-23 weeks. Dermal abnormalities such as pilonidal sinus, deep dimples, and scarred tissue were found in all six newborns. It is possible that the late regression of the embryonic human tail was the cause of these dermal findings.
六例胎儿经超声检查发现腰骶部有一强回声突出，提示产前诊断为人尾。所有胎儿均处于妊娠14 - 16周。所有病例在妊娠22 - 23周时超声检查结果均消失。在所有六名新生儿中均发现了如藏毛窦、深酒窝和瘢痕组织等皮肤异常。胚胎期人尾的晚期消退可能是这些皮肤表现的原因。
