Antenatal 3‐dimensional sonographic diagnosis of fetal oropharyngeal teratoma

Abstract

We report a case of a large fetal oropharyngeal teratoma in a 19-week fetus evaluated with 3-dimensional (3D) sonography. The 3D sonographic surface and maximum mode rendering of the tumor allowed detailed visualization of the mass lesion and thus enabled active patient participation in the management of the pregnancy.

First-Trimester Diagnosis of Fetal Epignathus With 2- and 3-Dimensional Sonography

“…The use of 3D sonography before mid gestation was reported to assist patients in making decisions about pregnancy continuation. 16,17 Three-dimensional rendering of the fetal facial surface has been previously shown to be feasible from 10 weeks' gestation. 18 However, one of the major pitfalls of acquiring a 3D volume in the first trimester is fetal movements, leading to inadequate volume rendering.…”
