A case of sirenomelia diagnosed after amnioinfusion / 대한산부인과학회지

Sirenomelia, also known as the mermaid syndrome, is a rare and usually lethal congenital malformation of uncertain etiology. It is characterized by fusion of the lower limbs and commonly associated with severe urogenital and gastrointestinal malformations. Early antenatal sonogram allows for earlier, and less traumatic termination of pregnancy, but usually it is impared by severe oligohydramnios related to bilateral renal agenesis. We diagnosed a sirenomelia with severe oligohydramnios at early second trimester after amnioinfusion and terminated. We report a case with a brief review of the literature.
