Baby born in Brazil with incredibly rare human ‘tail’

A baby in Brazil is one of the very few people to have ever been born with a ‘true’ human tail, doctors have revealed.

The baby boy was born with a 12cm tail, with a ball on the end, at the Albert Sabin Children’s Hospital in the city of Fortaleza in Brazil.

While scientists were shocked at the birth of the baby with such an appendage, they were successfully able to remove the tail and its ‘ball’ with surgery.

All babies develop an embryonic tail in the womb around four to eight weeks after gestation, but the tail is normally reabsorbed back into the body, which then results in the formation of a tailbone below the sacrum in the human body.

These appendages are composed of adipose, connective tissue, blood vessels, muscle, and nerve fibres.

There was no reason given as to why the tail didn’t get reabsorbed, but the doctors did note the mother had been treated for previous infections and that she had smoked 10 cigarettes a day while being pregnant.

Photos of the child’s “chain and ball” were released and it was published in the Journal of Pediatric Surgery Case Reports.

Even though the baby was born prematurely at 35 weeks, there were no additional complications apart from the tail and the ball protruding from him.

An ultrasound was performed and found there was little risk associated with the tail being attached to the child’s nervous system and thus a removal operation was performed. More details of how the tail and the ball was removed were not revealed by the doctors.

Following the removal of his tail, the team reported no further problems for the boy, and he was perfectly healthy.

In some faiths and cultures around the world, human tails are considered to be holy and are worshipped.
