Abstract
BACKGROUND

Facial teratoma is a rare benign tumor that accounts for about 1.6% of all teratomas and can be diagnosed by prenatal ultrasound (US). The purpose of this report was to describe our experience with the diagnosis of fetal facial teratoma by prenatal US at second trimester to provide a reference for clinical diagnosis of fetal maxillofacial teratoma.

CASE SUMMARY

We present two cases of patients with abnormal fetal facial findings on US at second trimester of pregnancy in our department. Case 1 was a 31-year-old G3 P1 + 1 female, with US revealing a heterogeneous echogenicity of 32 mm × 20 mm × 31 mm on the fetal face, most of it located outside the oral cavity and filling the root of the oral cavity. Case 2 was a 29-year-old G1P0 female, with fetal head and neck US revealing a cystic-solid echo mass measuring 42 mm × 33 mm × 44 mm, the upper edge of the lesion reaching the palate and filling the oral cavity. The contours of the lesions were visualized using three-dimensional (3D) US imaging. Both patients decided to give up treatment. Biopsies of the lesions were performed after induction of labor, and diagnosed as maxillofacial teratoma.

CONCLUSION

Fetal maxillofacial teratomas can be diagnosed by US in early pregnancy, allowing parents to expedite treatment decisions.

Core Tip: Facial teratoma is a rare benign tumor that accounts for only about 1.6% of all teratomas and can be diagnosed by prenatal ultrasound (US). In this study, we presented two cases of pregnant women with prenatally diagnosed fetal maxillofacial teratomas by US. The study highlights the value of prenatal US in the identification of maxillofacial teratoma in early pregnancy and describes the ultrasonographic features of these tumors.
