'''Sacrococcygeal teratoma''' (SCT) is a [[teratoma]] (a kind of tumor) located at the base of the [[coccyx]] (tailbone). It is thought to be a derivative of the [[primitive streak]].
[[Ultrasound]] is used to [[Diagnosis|diagnose]] sacrococcygeal teratoma in [[Pregnancy|second trimester]]. Mature sacrococcygeal teratomas tend to be [[Cyst|cystic]], showing [[anechoic]] component. Immature sacrococcygeal teratomas are much rare and solid type, showing [[echogenic]] mass within the [[pelvis]]. [[Echocardiography]] identifies high output [[Heart|cardiac]] state preceding [[hydrops fetalis]].
==Prenatal ultrasound==
 
During [[prenatal]] [[ultrasound]], an SCT having an external component may appear as a fluid-filled cyst or a solid mass sticking out from the fetus's buttocks. Fetal SCTs that are entirely internal may be undetected if they are small;  detection (or at least suspicion) is possible when the fetal bladder is seen in an abnormal position, due to the SCT pushing other organs out of place.

Overview

Ultrasound is used to diagnose sacrococcygeal teratoma in second trimester. Mature sacrococcygeal teratomas tend to be cystic, showing anechoic component. Immature sacrococcygeal teratomas are much rare and solid type, showing echogenic mass within the pelvis. Echocardiography identifies high output cardiac state preceding hydrops fetalis.
