ABSTRACT

Sirenomelia is a rare congenital malformation, characterized by early fusion (symelia) of the lower limbs, either complete or incomplete, resulting in a single limb resembling a mermaid. It is frequently associated with other malformations such as bilateral renal agenesis, anal imperforation, lumbosacral agenesis, single umbilical artery, renal or external genital dysplasia, as well as cardiac or neurological abnormalities. This malformation is fatal due to pulmonary hypoplasia or complications from associated anomalies. In this case, we report a rare case of sirenomelia in a 1-day-old newborn, hospitalized for the management of sirenomelia diagnosed postnatally, who presented with total symelia, absence of anus and genital organs, agenesis of internal organs, both kidneys, and the renal tract, and passed away on the second day of life, to highlight a rare malformation and the importance of prenatal diagnosis for obstetric monitoring, as well as the need to raise awareness about genetic counseling.
