Key result
Fetal teratomas carry a ~73% preterm birth rate, with pericardial tumors driving higher intervention.
Why the study?
The course and outcome of pregnancies with prenatally diagnosed fetal teratomas of various locations were evaluated to understand complications and intervention needs.
Population
79 pregnancies with prenatally suspected or diagnosed fetal teratomas at a single center between 2002 and 2019
Comparison
Outcomes and complications compared according to tumor location
Design
Retrospective observational single-center study

Fetal teratomas carry a high risk of complications such as polyhydramnios and cardiac compromise, often necessitating prenatal interventions to prevent preterm birth and intrauterine demise.
Simonini et al. (2020) conducted an observational in Fetal teratomas (n=79). Fetal teratomas vs. Different tumor locations was evaluated on Complications, need for intervention and outcomes. Among 79 pregnancies with fetal teratomas, preterm birth before 37 weeks occurred in 72.7%, and there was a significantly higher need for intervention in pericardial teratomas.
