Baby is born alive after growing in mother's abdomen for 29 weeks

MRI scan of a woman's abdomen shows a black arrow pointing at the outlined head of a fetus.

A woman in France went to the hospital with abdominal pain but soon learned that she was in the second trimester of a rare ectopic pregnancy, in which the fetus was growing in her abdomen.

Ectopic pregnancy refers to a phenomenon in which a fertilized egg implants somewhere other than within the uterus, and it occurs in around 2% of pregnancies. Ectopic pregnancies are most likely to occur in the fallopian tubes, the pair of ducts through which eggs travel from the ovaries to the uterus. However, around 1% of ectopic pregnancies occur within the abdominal cavity.
