Surgeons closed up the hole and removed the appendage.
Doctors from Grendaac, a children’s hospital in Sao Paulo, said the tail generated up from the lumbosacral region, the area that connects the spine to the pelvis.

Medics diagnosed the appendage as a “human pseudo-tail”, a growth that resembles a tail but are caused by spine problems or tumours.
The deformity is different to a tail, which contains muscle, blood vessels and nerves but no bones.
Researchers from the Centre for Fetal and Placental Research in Ohio studied the case alongside Brazilian doctors.
“Human caudal appendages are rare lesions that impose an enormous stigma on their carriers and parents,” they wrote.
“Fetal caudal appendages are associated with spinal dysraphisms (spina bifida), and its presence therefore mandates careful screening for underlying spinal cord defects.
“Identifying of the numerous possible associated anomalies is critical to plan the correct treatment and offer good quality counseling [sic].”
