Abstract: Sirenomelia or the Mermaid syndrome is a rare congenital anomaly with an incidence of one 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. A 37-week, 3040-g infant was born to a 35-year-old multigravida mother with type 2 diabetes mellitus and hyperlipidemia. To our knowledge, this is the first case of sirenomelia with adrenalomegaly.
