摘要

胎兒骨氐尾骨畸胎瘤為極罕見的胎兒腫瘤，其發生機率約為四萬分之一。通常在產前檢查時發現此腫瘤約為懷孕22週以後。一般當胎兒患此疾病時會提高胎兒的死亡率及併發症，其中胎兒骨氐尾骨畸胎瘤極少合併染色體異常、嚴重畸形或惡性轉變；引起產前胎兒死亡機制包括有胎兒心衰竭、早產、難產、腫瘤破裂而造成的大量出血；本文報告一位懷孕17週於進行產前檢查時隨即診斷出胎兒骨氐尾骨畸胎瘤的案例和產前診斷及治療的文獻回顧。

Sacrococcygeal teratoma is a rare fetal neoplasm with an incidence of 1 in. 40,000 births. Antenatal diagnosis is usually made after 22 weeks of gestation. Fetuses with this malformation are at risk of significant perinatal morbidity and mortality. Malignant components, coexisting with life-threatening anomalies, and chromosomal abnormalities are rare. Postulated causes of perinatal death include hydrops, dystocia, tumor rupture, preterm labor secondary to polyhydramnios, and anemia due either to hemorrhage or hemolysis within the tumor. Herein, we present a case of fetal sacrococcygeal teratoma diagnosed as early as 17 weeks of gestation.
