A baby girl in Hong Kong was found to be “pregnant” with two tumors in her abdomen which were later found to be the fetuses of twin babies.
The Chinese baby born in Queen Elizabeth Hospital in Hong Kong had to undergo surgery at 3 weeks old to remove the fetuses that were believed to be at 8 to 10 weeks of gestation.
The fetuses each had four limbs, a spine, rib cage, intestines and anus, but were different in weight, one weighing 14.2 grams and the other 9.3 grams, each had an umbilical cord connected to a single placenta-like mass.
In a report from the South China Morning Post, doctors said the baby girl was born with a rare condition called “fetus-in-fetu,” which occurs only about 1 in every 500,000 births.
“Since it is impossible for the little girl to have conceived the pregnancy on her own, the fertilization of the twin fetuses, of course, belongs to her parents, which has gone to the wrong place,” Dr. Yu Kai-man, a specialist in obstetrics and gynecology, was quoted as saying in the report.
Aside from the possibility of being pregnant with triplets, researchers hypothesize the condition was triggered by either the mom having more than one previous abortion, or that the mass is a teratoma —— a non-cancerous tumor containing tissue, hair, and even teeth.
