Abstract:
Objective To explore prenatal ultrasonic findings of fetal anterior neck cystic mass.Methods Thirty-one fetuses with cystic masses at anterior neck region and underwent systematic or targeted prenatal ultrasound with pathological diagnosis and completed follow-up were retrospectively collected.Prenatal ultrasonic findings were analyzed,and the clinical outcomes were recorded.Results Among 31 fetuses with anterior neck cystic mass,21 were confirmed as lymphatic cysts,which appeared as lateral cystic masses at the anterior neck on prenatal ultrasound,some with a wide size that could cross the midline,often accompanied by septations.Thyroglossal duct cyst in 6 fetuses presented as single-chambered thick-wall(≥2 mm)cyst on the left side of fetal anterior neck with good acoustic transmission within the cyst.Dermoid cysts in 2 fetuses presented as cyst located in the midline subcutaneous area at the base of the mouth.Thyroglossal duct cyst in 1 fetus presented as thin-wall cystic echo on midline at the anterior neck with clear margin,regular shape and mobility during swallowing.Esophageal atresia in 1 fetus presented as an elongated cyst in the anterior neck region,with changeable shape when swallowing,accompanied by small gastric bubbles and polyhydramnios.Lymphatic cysts in 4 fetuses complicated with systemic edema,cardiac malformations,holoprosencephaly,cleft lip and palate,diaphragmatic hernia and macroglossia,1 fetus with esophageal atresia had anomalies including absence of the left kidney,persistent left superior vena cava,and single umbilical artery,and the above 5 leaded to termination.The rest 26 fetuses continued until parturition,and received surgical,interventional,pharmacological treatments or close monitoring,all had good prognoses.Conclusion Prenatal ultrasound could clearly show the location,shape and intracapsular echo of fetal anterior neck cystic masses,being helpful for prenatal diagnosis,consultation and postpartum sequential treatment.
