A Case of an Epignathus with Intracranial Extension Appearing as a Persistently Open Mouth at 16 Weeks and Subsequently Diagnosed at 20 Weeks of Gestation

Publication at First Faculty of Medicine |


We report a rare case of oral mass (epignathus) with intracranial extension originally suspected antenatally at 16 weeks' gestation because of a persistent open mouth. Postmortem MRI and pathologic examination of the fetus confirmed an oral teratoma with bilateral ventricular dilatation, corpus callosum agenesis, and a neuroepithelial intracranial cyst.

The relevant literature regarding this anomaly is reviewed.
