A two-year-old boy from Huaxi, has undergone an
operation to give 'birth' after doctors diagnosed him as 'pregnant'. Xiao Feng,
was brought to hospital after his stomach had become so distended that he had
begun to suffer breathing difficulties. Once admitted, doctors took x-rays and
MRI scans and discovered that Feng was carrying the undeveloped foteus of his
own twin inside his stomach and they rushed him to surgery.
The
removed foetus measured 20 cm in width and had a fully formed spine and limbs,
including fingers and toes. Identical twins form when an egg splits in half
after fertilization. But conjoined twins or foetus-in-foetu siblings occur when
the egg fails to fully separate.
Dr
Jonathan Fanaroff, a neonatologist at Rainbow Babies and Children’s Hospital in
Cleveland, said some conjoined twins can survive as 'parasites', but not when
one twin absorbs the other.
