Falsely diagnosed umbilical edema due to necrotizing funisitis during prenatal ultrasound examination as an umbilical cord cyst corrected by postpartum histological test

• Kim CH

Abstract

Umbilical cord cyst is correlated with the fetal chromosomal defects or its structural abnormality; therefore, the follow-up evaluations on fetal growth, lesion size, and concomitant congenital malformation are essential. Thus, when a prenatal ultrasonogram suspects an umbilical cord cyst, karyotyping is strongly recommended to rule out any chromosomal abnormality. The pathologic findings of necrotizing funisitis are paraumbilical exudates due to inflammatory changes, the secondary calcification change of the exudates, thrombosis, and sometimes edema of the umbilical cord. Even though incidence of umbilical cord cyst is rare, it must be differentiated from a cord edema caused by necrotizing funisitis. We have encountered a patient with a suspicious umbilical cord cyst in the third trimester of her pregnancy but the postpartum diagnosis turned out to be an umbilical cord edema by necrotizing funisitis, so we investigated the case with brief comparison to other literature.
