Prenatal diagnosis of fetal umbilical cord teratoma

Abstract

Umbilical cord teratomas are rare tumoral lesions of umbilical cord which have challenging antenatal diagnosis. The cord teratomas contain tissue from all three germ layers and have both cystic and solid components. This ultrasonographic appearance may help the clinician to clarify the correct diagnosis. We report a case of cord teratoma diagnosed prenatally by ultrasonography and magnetic resonance imaging. Since cord teratomas may lead to adverse fetal outcomes, close follow-up of the fetus is recommended.
