First-trimester diagnosis of sacrococcygeal teratoma: The role of three-dimensional ultrasound

Abstract

A fetus was suspected of having a sacrococcygeal teratoma (SCT) on routine nuchal translucency evaluation by sonography at 12+3 weeks. The patient was referred for three-dimensional (3D) sonography to further delineate the extent of the mass. In this case, real-time scanning of the mass in 3D mode assisted the diagnosis of the mass and patient counseling. We present what we believe to be the first case of SCT imaged in the first trimester using 3D ultrasound. Copyright © 2004 ISUOG. Published by John Wiley & Sons, Ltd.
