A devastated mum in China is begging doctors to help her seven-month-old son - who has a three-inch tail sticking out of his back.
Little Xiao Wei was born with spina bifida, which means his vertebrae didn't form properly.
The result is a growth that protrudes out of the back of his spine and is still growing.
Xiao's mum Chen, from Guangdong province, revealed: "We have asked the surgeons to remove the tail but they tell us it is not that simple."
Surgeon Huang Chuanping explained: “The growth is quite well developed and now measures some 10 centimetres.
“If we cut it off it will simply grow again. We need to repair the spinal canal first to stop it reoccurring."
Myelomeningocele is the most common type of spina bifida, affecting 1 in 800 babies born.
