Purpose or Case Report: The purpose of the pictorial review is to aid in understanding and identifying the spectrum of possible congenital oral lesions and make the radiologist familiar, as early detection of these is required to avoid potential perinatal and postnatal complications.

We performed a retrospective review of radiology reports from our pediatric hospital system, inclusive of our fetal imaging center, focusing on congenital oral lesions with prenatal or postnatal diagnoses. Utilizing multiple keywords through our radiology report data mining software, we reviewed cases over the last 15 years and grouped lesions based on the most likely diagnosis. Available prenatal and postnatal imaging, clinical management, and pathology was reviewed.

Our review of cases yielded both common congenital oral lesions, such as hemangiomas, as well as more extensive malformations and tumors of the face extending to the oral cavity. Lesions such as epulis, oral duplication cysts, and lingual ectopic thyroid were rarer in our review, but have imaging characteristics important to recognize by the radiologist. We selected representative images from the spectrum of congenital oral and outlined radiology and clinical teaching points.
