A two-year old Chinese boy had to undergo surgery so he could "give birth" to his parasitic twin brother. Doctors in China were shocked to discover that the foetus of the boy's parasitic twin was living inside his stomach.

Xiao Feng was rushed to the hospital after he was having a difficult time breathing due to an enlarged stomach. The boy, who is from Huaxi, was examined by doctors and his MRI scans and X-Rays revealed that he was carrying his twin brother inside his big stomach.

The stunned doctors rushed the "pregnant" Chinese boy into emergency surgery. Doctors immediately removed the "twin brother" from the boy's stomach to save his life.

The foetus measured 20 cm and already had fingers, toes and a spine. The parasitic foetus had took up most of the boy's stomach as room to grow. This rare case of conjoined twins is known as cryptodidymus.

According to the Inquisitr, it is extremely rare in medicine. Conjoined twins are formed when the fertilized egg does not completely separate. Identical twins are formed when a single egg breaks apart during fertilization. A "parasite" twin fetus can survive but not when one fetus absorbs the other.

According to doctors, removing parasitic twins is easier than trying to separate conjoined twins because the heart, lungs and brain are the last to form in the body.

In another case in 2012, doctors in Peru removed a 9-inch long parasitic twin from a three-year-old boy that weighed one pound and half. Dr Carlos Astocondor at Las Mercedes Hospital in the northern area of Chiclayo said the condition of having a parasitic twin occurs in one for every 500,000 births.
