A One-Year-Old Girl Had Her Twin Growing Inside Her Brain

 

"Doctors in China found an “unborn twin” in the brain of a one-year-old child in China, according to a new study. The study published in Neurology journal in December revealed that the child was brought in after she presented problems with motor functions and had an enlarged head. A 1-year-old girl in China was having difficulty with her motor functions. Her head was enlarged, and she wasn’t developing at the rate expected for a child her age. Doctors decided to take a closer look, and when they took an X-ray of her skull, they saw bones in a sac inside her brain. The case study, published in the scientific journal-Neurology in December, said the phenomenon was an intraventricular fetus-in-fetu. Fetus-in-fetu, sometimes called a parasitic twin, occurs when twins become conjoined in utero, but only one continues to develop. The undeveloped twin is often absorbed into the body of the developing twin. But absorption into the brain is extremely rare. Doctors decided the parasitic twin needed to be removed for the health of the 1-year-old. What they removed was a fetus, about 10 centimeters long, with the beginning formations of arms and hands. The fetus had a spine, but remained extremely undeveloped. The doctors called it a “fetiform,” a type of growth that resembles a fetus. When they ran DNA tests on the growth, they confirmed it was the twin of the living girl that had been absorbed during a developmental process called neural plate folding, a step necessary for the structure of the brain and spinal cord. This would explain how the parasitic fetus ended up inside its sister’s skull. The parasitic twin was around 10 centimeters long and had arm and hand structures, the doctors said. It might sound like something out of a horror movie, like the 2021 film “Malignant,” where a parasitic twin controls the living twin from inside her head, making her kill on his command." Based on size and development, the unborn twin was roughly the size of a foetus at 10 weeks.
