Sirenomelia: A Rare Entity.

Sirenomelia also called as Mermaid Syndrome, is a rare congenital malformation of uncertain aetiology. It is characterised by fusion of the lower limbs and commonly associated with severe urogenital and gastrointestinal malformation. It should be suspected in antenatal period in cases presenting with severe oligohydramnios and intra-uterine growth retardation. Here, we report a case of sirenomelia in a 26th weeks foetus.
