The role of prenatal ultrasound assessment in management of fetal cervicofacial tumors.

Ultrasound prenatal examination enables one to assess the facial skeleton and the neck from the first weeks of gestation. Cervicofacial tumors detected via prenatal ultrasound are very rarely reported fetal pathologies. They include cystic hygromas, teratomas, epulides, vascular tumors, and thyroid tumors. The tumor category, its location and vascularization pattern allow one to accurately establish a diagnosis which is usually confirmed by clinical examination of the neonate or a pathological examination (surgical specimen, biopsy, autopsy). The prenatal ultrasound diagnosis of cervicofacial tumor in the fetus allows planning of pregnancy management and fetal therapy, preparation of the delivery, and perinatal as well as neonatal treatment.
