In a surprising medical case, doctors in Shanghai, China found a fetus growing in the skull of a one-year-old girl.
A child with this unusual disorder, known as fetus in fetu (FIF), had severe developmental problems and showed significant delays in speech and motor development.
Early symptoms and diagnosis
The parents took the one-year-old girl to the hospital after realizing her developmental deficits.
During a CT scan of her head, doctors discovered a large lump in the cerebral hemisphere. This mass, which had a smooth margin and was 13 centimeters in diameter, had internal bony features.
Abnormalities in pregnancy
A 33-week prenatal test revealed abnormalities, but due to the space occupied in the skull, the MRI was unable to provide accurate information. The girl had a high head circumference and gave birth by cesarean section at 37 weeks.
Fetus in Fetus: Understanding
A rare developmental abnormality known as “fetus in fetu” occurs when a deformed fetus develops inside its twin’s body. It had about one in every 500,000 live births. FIF is usually detected in the abdomen, but in this case, it was discovered in the skull. 3. According to study authors Xuewei Qin and Xuanling Chen of Peking University International Hospital, “FIF remains a mystery,” pointing to potential genetic and environmental causes.
Surgical procedure
Due to the patient’s serious condition, doctors decided to perform a craniotomy, a surgical procedure that exposes the brain by removing part of the skull. During the operation, they found a deformed fetus with visible limbs, mouth, eyes, and other organs.
“After complete mass resection, the shapes of the mouth, eyes, arms, and hands could be observed,” the research states.

Obstacles in surgery
Despite thorough pre-operative preparation and examination, the one-year-old girl had uncontrollable convulsions after the procedure. Unfortunately, she died 12 days after the procedure, still unconscious. The only curative treatment for such situations is surgical resection, and the prognosis is typically dismal.
Research and Implications
The necessity of early identification and treatment emphasizes the rarity of patients with intracranial FIF. Effective medical intervention requires the ability to differentiate FIF from other disorders such as teratomas.
“Monitoring alpha-fetoprotein levels after surgery may help detect recurrence,” the researchers found.
Case Study Reflections
Fewer than 200 cases of FIF have been documented in the medical literature, and this case adds to that number. It emphasizes how essential sophisticated imaging methods and prenatal care are to the identification and treatment of such unusual disorders. Important insights can be gained from the experience of doctors in Shanghai about the difficulties in identifying and treating FIF.
In conclusion
The discovery of a fetus growing inside a child’s skull is a remarkable reminder of the mysteries of human development and the unexpected challenges it can present.
Cases of “fetus in fetu” (FIF) are extremely rare, especially when localized in the skull, as they typically develop in the abdominal area. This particular case, seen in a one-year-old girl in Shanghai, sheds light on the limits of prenatal detection and the critical importance of early intervention in the management of developmental abnormalities. Despite prenatal scans showing irregularities, an accurate diagnosis could not be confirmed until after birth, highlighting the need for advances in fetal imaging and diagnostic tools.
The surgical challenges encountered in this case also underscore the difficulties physicians face in treating such complex conditions. Although doctors performed a craniotomy to remove the mass, the girl’s condition remained uncertain. Tragically, despite their best efforts, she succumbed to complications shortly after the operation. This result illustrates the limitations of medical intervention in cases involving rare abnormalities and the significant risks associated with complex brain surgery at such a young age.
This case further highlights the need for further research to better understand the causes and optimal treatment of FIF. Both genetic and environmental factors may play a role, but these remain largely unexplored. For practitioners, differentiating FIF from similar disorders such as teratomas is essential to providing effective treatment, as each diagnosis may require a different approach. In the wider medical community, this case serves as a call for the development of advanced diagnostic techniques, comprehensive surveillance, and continued investigation into the origin and treatment of FIF.
Ultimately, the Shanghai case not only adds to the limited number of documented cases of FIF but also serves as a poignant reminder of the human body’s potential for both wonder and vulnerability.
