Sacrococcygeal teratoma SCT is one of the most common fetal neoplasms with an incidence of around 1/27000 live births with female-to-male ratio of 4:1. A 37-year-old multigravida was referred for evaluation of a fetal presacral mass that was seen on ultrasonography US at 21 weeks’ gestation. A female fetus presenting with a heterogeneous, solid mass with cystic components, measuring approximately 8x7x7.5 cm starting from sacral region was detected. The couple elected to terminate the pregnancy, and postnatal findings confirmed the diagnosis of SCT. Three dimensional ultrasound is a valuable adjuvant to routine B-mode sonography for antenatal diagnosis of SCTs and can define the degree of involvement of the sacrum. It is also a useful tool to map out the vascularity of fetal SCTs and thus allows visualization of the blood flow between SCTs and fetal circulation and enables parents to visualize the lesion.

Sakrokoksigeal teratom en sık gözlenen fetal tümörlerdendir. İnsidansı 27.000 canlı doğumda bir olup, kızlarda yaklaşık 4 kat daha fazla görülür. 37 yaşında, multigravida, 21 haftalık gebeliği olan hasta dış merkezden presakral kitlenin araştırılması için perinatoloji kliniğimize yönlendirilmiştir. Kız fetuste sacral bölgededen başlayan yaklaşık 8x7x7.5 cm lik heterojen, yer yer kistik komponentler içeren solid bir kitle izlendi. Aile gebeliğin sonlandırılmasını seçti ve postnatal tanı SCT ile uyumluydu. 3 boyutlu görüntüleme, SCT tanısında ve sakrumun invazyonun değerlendirilmesinde rutin B-mod sonografiye yardımcı olur. Ayrıca tümörün vasküleritesinin detaylandırılmasında, fetal dolaşım ile tumor arasındaki kan akımının görüntülenmesinde ve ailenin lezyonu, gözünde daha iyi canlandırmasında kullanışlı bir araçtır.
