Imagine discovering that a 1-year-old girl had a fetus growing inside her skull. This heartbreaking and rare medical condition, known as “fetus in fetu,” recently came to light in China. It is apparently, a twin that has been growing inside the skull. Signs of abnormalities were present even when the mother was pregnant with the 1-year-old girl. The girl had an unusually large head at the time of her birth.
According to the British Medical Journal, less than 200 cases of fetuses in fetuses have been reported globally. Even more astonishingly, only 18 cases have been found inside a person’s skull.
The Case of the Girl in China: Discovering a Twin Inside The Skull!
The initial signs of abnormalities were detected during the mother’s pregnancy at 33 weeks. Doctors noticed something unusual during a routine check-up, but the caesarean birth went ahead without significant issues, despite the baby’s larger-than-average head.
Around a year later, the child was brought to Peking University International Hospital in Beijing due to concerns about her development. She had swelling in her head, difficulty standing, incontinence, and could only say a few words, like “mom.” These symptoms prompted further medical investigation.
Medical Examination and Surgery
Doctors discovered a 5-inch mass (13 cm) inside the girl’s skull. This mass contained bone fragments and other fetal features like eyes, hair, forearms, hands, feet, and a mouth.
During the surgical procedure to remove the mass, doctors also found a spine and bones inside a white capsule full of brown liquid. Unfortunately, the surgery led to severe brain tissue compression, causing seizures. Despite their best efforts, the young girl was removed from life support after 12 days.
Understanding Fetus in Fetu
Fetus in fetuses is a rare developmental abnormality where a mass of tissue resembling a fetus forms inside the body of its twin. Historically, it was first described in 1808 by George William Young. The condition is estimated to occur in about 1 in 500,000 live births.
There are two main theories about the origins of fetuses in fetuses. One theory suggests that the mass starts as a normal fetus but becomes enveloped inside its twin. The other theory proposes that the mass is a highly developed teratoma, an abnormal collection of cells. The exact cause remains a mystery.
Fetus in fetuses can typically be detected during pregnancy using ultrasound. According to the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG), it usually appears as a complex mass with clear borders inside the baby’s abdomen. The mass often contains a fluid-filled sac with solid elements or bony structures within. There can also be calcifications inside the mass.
Medical and Scientific Insights
The study by Peking University International Hospital, published in the American Journal of Case Reports, highlights the medical and scientific significance of this rare condition. The findings from this case contribute to the limited but crucial knowledge about fetuses in fetuses.
Other rare instances of fetuses in fetuses have been reported, particularly those involving the skull. For example, in 2015, a 20-day-old child in China was found to have a fetus in its scrotum, which was successfully removed. These cases emphasize the rarity and severity of the condition, making each new discovery important for medical research.
Conclusion
This story of a young girl in China is both heartbreaking and fascinating. From the initial discovery of abnormalities during pregnancy to the developmental delays and tragic outcomes after surgery, her case sheds light on the rare condition of fetuses in fetuses.
