DOCTORS treating a baby girl suffering from stomach pain were left stunned to find she had her unborn twin inside her tummy.
Medics made the bizarre discovery while operating on the ten-month-old tot, intending to remove an abdominal tumour.
But they were blown away when they discovered the growth in her stomach was actually her twin.
The extraordinary case, known as fetus in fetu, left surgeons at a hospital in the city of Sadiqabad in Pakistan stunned.
Medical chiefs explained the little girl had initially been admitted for treatment after suffering severe abdominal pain.
