Prenatal Ultrasound Diagnosis of a Cyst of the Oral Cavity: An Unusual Case of Thyroglossal Duct Cyst Located on the Tongue Base

We describe a case of a lingual thyroglossal duct cyst diagnosed prenatally by ultrasound at 26 weeks of gestation. The follow-up ultrasound scans revealed no changes in the cyst measurement. Surgical treatment was performed without any complication 72 hours after delivery with good results.

Imaging of pediatric floor of mouth lesions

There is a vast spectrum of pathology that afflicts the floor of mouth in children. These span inflammatory conditions, vascular malformations, developmental anomalies, benign tumors and malignancies. While this area is readily evaluated on clinical exam, imaging is often performed to better characterize the disorder prior to management. The imaging modalities most frequently utilized are US, CT and MR. The purpose of this article is to describe the primary conditions that occur in this location in children so that radiologists may provide an appropriate differential diagnosis. These include ranula, venolymphatic malformation, dermoid, teratoma, foregut duplication cyst, hairy polyp, thyroglossal duct cyst and rhabdomyosarcoma. For each pathological condition, there will be a focus on describing its imaging manifestation. Floor of mouth anatomy, imaging approach during both prenatal and postnatal life and etiologies will be discussed. Surgical considerations and operative photographs will also be presented.
