Cystic hygromas are manifestations of early lymphatic failure. They appear as simple or multi-septated fluid collections, most commonly at nuchal region. Prenatal diagnosis of cystic hygroma can be made within 2nd trimester of pregnancy. Hydrops fetalis is defined as accumulation of fluid in serous cavities and/ or edema of soft tissues in the fetus. Incidence of fetal hydrops is approximately 1 in 2500 to 3500 neonates with incidence co-existence of hydrops and cystic hygroma even rarer. We here present a case of a fetus of 14 weeks gestational age with diagnosis of large cystic hygroma complicating to fetal hydrops.
