Surgeons in Montreal performed a C-section and found a baby managed to grow and develop outside his mother's uterus.

Dionne Grant, 29, and her newborn son should be going home later this week. Although she is camera shy, Grant wanted the world to see her baby. He does not yet have a name.

Dr. Robert Sabbah, head of obstetrics and gynecology at Sacré-Coeur Hospital, said he only discovered the problem after deciding to perform an emergency caesarean section on the Jamaican tourist last week.

"When I opened the cavity I quickly discovered that the uterus was not like it was supposed to be," said Sabbah.

"As soon as I explored the abdominal cavity I noticed there were feet in the cavity just floating around. So as fast as I could I took out the baby."

He said that abdominal ectopic pregnancies occur in one in 10,000 pregnancies. In 99 per cent of the cases, the babies die. There are only a dozen similar cases in the world, according to obstetricians.

Doctors believe the baby survived because the placenta glued itself to the top of the uterus, accessing blood to nourish the baby.

Sabbah said he's thrilled to have been part of the surgery and even more thrilled that both his patients are doing so well.
