Milagros Cerron came into the world in April 2004, in Huancayo, Peru, her fused legs a shock to everyone in the delivery room. Her mother had never gone for an ultrasound prior to the baby’s birth, so she had no idea what her baby would look like.
Doctors, on the other hand, couldn’t believe the baby had survived birth. Infants born with her condition, known as sirenomelia or “mermaid syndrome,” have a very high mortality rate. That’s because the condition causes complications in the kidney and bladder, too.
Dr. Lindsey Fitzharris, a medical historian, told the Mail Online that there is very little information about the history of mermaid syndrome, and “there are no accounts of anyone with this condition surviving in the past.” She added, “Even today, the odds are against those with sirenomelia.”
