Large Oropharyngeal Teratoma Diagnosed Ante-Natally Using Foetal 3D Ultrasound Scan and MRI: a Case Report

A case presentation of a rare condition of foetal oropharyngeal teratoma suspected by antenatal 3D ultrasound scan and foetal MRI at 30 weeks gestation. The tumour originated in the oropharynx and grew through the open jaw into the amniotic fluid causing obstruction and polyhydramnios. The baby was delivered through a pre-term emergency Caesarean section at 31 weeks gestation followed by postnatal MRI that confirmed the diagnosis. The outcome was early neonatal death as a consequence of respiratory distress and neonatal sepsis.
