A baby girl named Itzmara was born through a cesarean delivery, and 24 hours later, doctors performed a C-section on her too, because she had absorbed her twin in the womb, Mamás Latinas reported in March.
When the mother, Mónica Vega of Barranquilla, Colombia, had an ultrasound at seven months pregnant, doctors discovered she had two umbilical cords inside her. One connected baby Itzmara to Vega, but the other connected Itzmara to a mass that was her parasitic twin.
When doctors noticed this, they diagnosed Itzmara with “fetus in fetu,” a rare condition where a malformed fetus is found in the body of its twin. The doctors said they needed to deliver Itzmara right away through a C-section so they could then operate on the baby. They were worried that if they didn’t remove the parasitic twin inside Itzmara, the mass could grow and injure the baby’s organs.
So after delivering Itzmara via C-section, the doctors performed a C-section on her too to remove the mass, which had no heart or brain. Itzmara was in good health following the surgery, Mamás Latinas reported.
The baby’s condition is extremely rare
According to the National Institutes of Health, fetus-in-fetu is very rare, with only one case occurring in about every 500,000 births. Additionally, authors of one fetus-in-fetu case study published in August said only 200 previous cases of FIF had been documented in medical journals.
