Doctors baffled by the birth of a baby with a strange 12 cm “human tail”

A baby Born prematurely at 35 weeks surprised a group of doctors in Brazil by presenting a strange “human tail” of twelve centimeters, according to a report in the Journal of Pediatric Surgery Case Reports. The case was documented at the beginning of the year at the Albert Sabin Children’s Hospital (HIAS) in Strength capital of the state of Ceará, and this week it gained worldwide media relevance.

The condition, registered for the first time in the South American giant, it is a rare congenital anomaly, the authors note.

According to the report’s description, a “fibroelastic appendix” was supported by this tail (“a fibrous cord”), which emerged from the left lumbosacral paraventral region. The doctors had to perform removal surgery.

The following images may affect the sensitivity of some readers.

Before performing the procedure, the baby underwent multiple evaluations, as “lumbosacral skin appendages and other skin lesions are an important indication of nervous system involvement,” says the report.

“After clinical analysis and imaging tests, we did not identify any neurological components. This made the removal surgery less complex, ”explained Humberto Forte, a resident pediatrician who participated in the procedure, in dialogue with the newspaper O Povo.

While they are in the womb, babies develop an embryonic tail between the fourth and eighth weeks of gestation, which is normally reabsorbed by the body. In the case of the baby from Fortaleza, it continued to grow and even developed a ball-shaped appendage four centimeters in diameter at the end.

“There is still no concrete cause defined. The most accepted theory is an alteration in the regression of the embryonic tail that we all have during our development phase. However, the etiology of the alteration has not yet been defined ”, points out Forte.

The abnormality can be identified during pregnancy through a quality ultrasound (USG), according to the specialist.

Globally, only 40 similar cases were recorded, the first of which dates back to the 19th century.
