Abstract
Sirenomelia, the Mermaid Syndrome is a rare and lethal congenital anomaly with an incidence of 1 in 60,000 to 70,000 pregnancies. Sirenomelia is characterized by complete fusion of the lower limbs, commonly associated with renal agenesis, absent external genitalia and other gastrointestinal defects. Another pathognomonic finding is the presence of single umbilical artery (persistent vitelline artery) which is the chief distinguishing anatomic finding from Caudal Regression Syndrome. We report a case of rare fetal anomaly which was identified to have characteristic features of Sirenomelia at the time of delivery.
