A case report of sirenomelia with two umbilical arteries: an
Sirenomelia also known as Mermaid syndrome is a rarely encountered fusion anomaly of the caudal region of the body often associated with Potter’s facies, single umbilical artery, and various visceral abnormalities which make it irreconcilable with life.

Here investigators report a case of sirenomelia delivered in the tertiary care hospital by lower segment cesarean section to a 24-year-old third gravida with no previous live issues. No high-risk factors could be identified with the mother including diabetes mellitus.

The baby was born alive with Potter’s facies. Both the lower limbs were merging into each other like a mermaid’s tail (hence called mermaid syndrome). The sex of the baby could not be identified and the urogenital and anal orifices were absent. The umbilical cord stump had two umbilical arteries. The baby died after 20 hours of life.

There appears to be no definitive modality for diagnosing sirenomelia in the antenatal period. However, if a patient has consistently low AFI without any history of leaking per vaginum, a high-resolution USG or color Doppler should be done at the earliest to look for the cause.
