BACKGROUND Lymphatic malformations are benign cystic lesions that, while rare, tend to affect the pediatric age group. There are no reported cases diagnosed prenatally. CASE A 28-year-old G1 woman at 34 weeks gestation was scanned for placental localization at a community ultrasound clinic. A fetal cystic, sublingual structure was identified. The patient was referred to our tertiary care centre, where a small (1.3 cm) avascular, cystic structure under the tongue of the fetus was confirmed. Antenatal course and delivery were unremarkable. The lesion resolved spontaneously with time. CONCLUSION This report highlights a unique case in which a sublingual lymphatic malformation was detected prenatally during a third-trimester ultrasound.
