[Pharyngeal epignathus teratoma. Echographic and prognostic study]

Pharyngeal epignathus teratoma is an isolated benign tumour, but the prognosis is very indeed because it can so easily obstruct the respiratory or the digestive pathways. Only rarely has this teratoma been diagnosed by ultrasound in the literature. The authors, having had a personal case, decided to discuss the problems in making the diagnosis by ultrasound and in deciding what treatment to carry out.
