The fetal kariotype was normal. Follow-up ultrasound scans revealed no changes in the size or the position of the cyst. Fetal growth was normal as was the amniotic fluid volume. Surgical treatment was performed 3 days after a normal vaginal delivery, with excellent results.porRânula CongénitaRecém-NascidoUltrassonografia Prenataljournal article
