Cystic hygroma has an incidence rate of 1 case per 1000 birth. Half of cystic hygroma may have chromosomal abnormalities, and demonstrate poor prognosis. We experienced two cases of cystic hygroma and report with a literature review. Case 1 is a 37-year-old woman. Transabdominal ultrasonography at 12 weeks of gestation demonstrated bilateral cysts at neck, and diagnosed as cystic hygroma. No abnormal findings are detected by amniocentesis. With a request for artificial abortion, vaginal delivery was performed. Case 2 is a 28-year-old woman. Thick nuchal translucency was detected at 12 weeks of gestation. There were bilateral cysts at neck, and diagnosed as cystic hygroma. Amniocentesis revealed the inversion of chromosome 13. With a request for continuing pregnancy, regular prenatal visits have been performed. Half of cystic hygroma may have chromosomal abnormalities. Based on its natural history with decision of performing amniocentesis, providing appropriate information through ultrasonography can be extremely useful.
