Boy's foetus twin shock

PLEASE NOTE: EDIT CONTAINS CONVERTED 4:3 MATERIAL
At first sight three-year-old Isbac Pacunda seems like any ordinary toddler.
On the inside he's got a rare condition - what doctors call a parasitic twin.
Surgeons in Peru found the 25-centimetre long foetus in Isbac's stomach after he complained of pains.
SOUNDBITE: Doctor Marco Antonio Flores saying (Spanish):
"Through giving him an ultrasound scan we realised that he had bones inside - a humerus, a femur, a backbone. Then we did another ultrasound that confirmed the diagnosis."
Doctors say a parasitic foetus has no brain, heart or lungs but lives off the blood supply of its host.
The condition happens in about one in every half million births.
Its removal is a complex process, but Isbac at least is likely to feel the benefit after three years as the unwitting host of a twin he never knew existed.
