This one comes from Bangladesh, according to the BBC:
Doctors in Bangladesh say they have removed a long-dead foetus from the abdomen of a teenage boy who was complaining of stomach pains.
They said the foetus would have become the boy’s twin had it grown normally in their mother’s womb.
They said it was a case of an extremely rare condition where two foetuses are conceived as conjoined twins but one absorbs the other.
In 2003 Kazakhstan doctors removed a foetus from a seven-year-old boy.
Sixteen-year-old Abu Raihan was admitted to the Bangabandhu Medical University hospital in the capital, Dhaka on Saturday.
“After the operation we found a dead foetus weighing two kilograms (4.5lbs) in his abdomen,” Doctor MA Mazid said, the AFP news agency reports.
“Apart from the head, all other limbs of the baby were developed.”
