A one-year-old girl underwent surgery to remove a mass from her brain, revealing a rare condition known as "fetus in fetu." This phenomenon occurs when one fetus is enclosed within another during development. In this case, the mass, measuring approximately four inches, contained upper limbs, bones, and fingernails, indicating it had been growing for months inside her cranial cavity.
A one-year-old girl underwent surgery to remove a mass from her brain, revealing a rare condition known as "fetus in fetu." This phenomenon occurs when one fetus is enclosed within another during development. In this case, the mass, measuring approximately four inches, contained upper limbs, bones, and fingernails, indicating it had been growing for months inside her cranial cavity. Fetus in fetu is a very rare occurrence, with only around 200 documented cases. It typically arises from the incomplete separation of identical twins during early development. One theory suggests that the healthier twin connects to the mother's placenta, while the smaller twin attaches to the larger twin's blood vessels. As the larger twin grows, it absorbs the smaller one into its body. The girl was admitted to the hospital due to motor skill issues and an enlarged head. CT scans revealed the fetus in fetu pressing against her brain, leading to hydrocephalus - a condition char...
