Abstract 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. Keywords Teratoma . Oropharyngeal . MRI
Introduction Teratomas generally constitute 25–35% of congenital tumours [1], with an incidence of 1/4000 births [2]. They most commonly affect the sacrococcygeal and gonadal regions while they rarely develop in the head and neck region, of which only 2% develop in the oropharynx [3], with an incidence of 1/35,000–1/200,000 births [4]. Congenital teratomas are usually benign and have a more predominance in female neonates [5]. We present a rare case of foetal oropharyngeal teratoma diagnosed ante-natally using ultrasound scan and MRI during evaluation of polyhydramnios at 30 weeks gestation and confirmed postnatally by MRI. The case ended up with pre-term emergency Caesarean section at 31 weeks following onset of

pre-term labour and followed by neonatal death at 2 days age because of respiratory distress and neonatal sepsis.
Case Presentation A 30-year-old female, gravid 3 para 2, who had a healthy boy and a healthy girl, was referred to Fetal Medicine Unit, Ain Shams University Maternity Hospital, Egypt, at 28 weeks gestation for evaluation of polyhydramnios. The mid-trimester 2D anomaly scan had been reported as normal. At 28 weeks gestation, on 2D ultrasound scan, polyhydramnios was confirmed with Deepest Vertical Pocket (DVP) more than 8 cm with a well-circumscribed heterogeneous mass in the oropharynx with poor filling of the stomach; otherwise, nothing was abnormal regarding foetal brain, heart, biometry or Doppler parameters. 3D ultrasound scan was done and only showed fullness in the outer surface of the lower jaw (Fig. 1). Progesterone was prescribed as a prophylactic measure to help preventing pre-term labour because of polyhydramnios and the woman was advised to come back on bi-weekly intervals for follow-up u
