Prenatal diagnosis, Cystic hygroma colli, Spontaneous regression
Cystic hygroma is the congenital malformation of the lymphatic system showing fluid-filled cavities around the neck. The antenatal diagnosis of cystic hygroma colli is not difficult with modern ultrasound equipment. The prognosis for fetuses with cystic hygroma, particularly in the presence of hydrops, is poor. Only a few cases of spontaneous resolution of the hygroma have been described. We report a case having a cystic hygroma colli with hydrops diagnosed at 25 weeks which regressed and manifested at term as loose skin at the infant's neck with no any other abnormal findings.
