Fetal cystic lymphangioma is a developmental anomaly of the lymphatic system, which can occur in any part of the body, but most commonly in the neck and armpit. A case of fetal cystic lymphangioma located at the chest wall under the right armpit with a size of 21 mm×18 mm×16 mm is reported here. The mass was initially diagnosed by routine ultrasound examination at 21 gestational weeks. After the diagnosis, ultrasound was repeated every 4 weeks till 37 +4 gestational weeks. Over this period, the mass increased progressively to 101 mm×110 mm×95 mm. Ultrasound-guided intrauterine fetal cystic mass puncture and aspiration was performed 38 +4 weekss, and Bleomycin was injected into the cyst after operation and on day 42 after birth. During a follow-up to 10 months after birth, no obvious cystic mass was found at the right axillary chest wall of the child.
