Non-mosaic trisomy 20 is rare in fetuses surviving beyond the first trimester. We report a case of a fetus with non-mosaic trisomy 20 in amniotic fluid cultures obtained during the prenatal evaluation of an unusual thoraco-abdominal mass which was found at autopsy to be pulmonary sequestration. Gross inspection and autopsy of the fetus revealed multiple anomalies.
非嵌合型20三体在孕早期后存活的胎儿中较为罕见。我们报告一例胎儿，在产前评估一个不寻常的胸腹部肿块时，羊水培养显示为非嵌合型20三体，尸检发现该肿块为肺隔离症。对该胎儿的大体检查和尸检发现了多种异常。
