New Delhi - A baby in India was born "pregnant" with his half-formed twin in a rare case that has astonished the medical fraternity in the country.
Some mass with the presence of bones was discovered early July in the then foetus' abdomen during a routine scan of the 19-year-old pregnant mother, said radiologist Bhavna Thorat.
"In the post-natal scans, we spotted another half-formed baby with a brain, arm and legs in a foetal sac in the baby's abdomen," Thorat said over phone.
"The mother had conceived twins. But here a twin got enveloped in the body of another twin, leading to a condition of a host baby and its parasitic twin, who grew up to 13 weeks and then stopped," she said.
This was a rare case of foetus-in-foetu, a congenital anomaly in which a malformed and parasitic foetus grows inside the body of a baby, Thorat added.
