Sacrococcygeal teratoma (SCT) is being diagnosed before birth with increasing frequency. We were recently consulted about management of a 22-week fetus with SCT and reviewed our experience (6 cases) and the literature. We found that most fetal SCT present from 22 to 34 weeks gestation with a uterus enlarged by the tumor and/or associated polyhydramnios; although the American Academy of Pediatrics Surgical Section clinical classification is an important prognostic indicator in neonatal SCT, it does not appear to predict outcome in fetal SCT; associated chromosomal abnormalities or life threatening anomalies are rare; presentation after 30-weeks gestation is a relatively good prognostic sign with fetal survival, after planned cesarean delivery, in 6 of 8 cases; and hydrops and/or placentomegaly in association with fetal SCT predicts fetal demise soon after diagnosis with 7 of 7 cases dying in utero.
骶尾部畸胎瘤（SCT）在产前被诊断出的频率越来越高。最近有人就一名患有SCT的22周胎儿的管理问题向我们咨询，我们回顾了自己的经验（6例）和相关文献。我们发现，大多数胎儿SCT在妊娠22至34周时出现，子宫因肿瘤而增大和/或伴有羊水过多；尽管美国儿科学会外科分会的临床分类是新生儿SCT的一个重要预后指标，但它似乎并不能预测胎儿SCT的结局；相关的染色体异常或危及生命的畸形很少见；妊娠30周后出现是一个相对较好的预后迹象，8例中有6例在计划剖宫产术后胎儿存活；与胎儿SCT相关的水肿和/或胎盘肿大预示着诊断后不久胎儿死亡，7例中有7例死于子宫内。
