During surgery to remove a 16-year-old girl’s appendix, surgeons discovered a surprise guest— a tumor with a brain, and the neurons that transmit electrical impulses as a normal brain.
The nearly 4-inch-wide tumor had also a thin plate of the skull bone coverage of the 1.18-inch brain, which also has a small version of a small brain and a mass that looked like a brain, New Scientist reported.
While it’s not uncommon for the brain cells to be found in the ovaries teratomas— tumors that contain foreign tissue including hair, teeth, cartilage, fat and muscle— this patient’s situation was unusual.
“Neural elements similar to those of the central nervous system are often reported in the ovarian teratomas, but the structures that seem on the adult brain are rare,” Angelique Riepsamen at the University of New South Wales in Australia, told the New Scientist.

It is not known what the cause of the ovarian teratomas, but one theory is that immature cells rogue and produce different parts of the body, New Scientist reported.
Fortunately, the nameless patient is not suffering from the symptoms, but neurological symptoms can occur when the immune system labels the brain cells in the ovary as foreign and attacks, while also attacking the cells in the woman is the real brain. Other cases have reported that the women with the unusual tumors have developed, personality changes, paranoid thoughts, confusion, agitation, convulsions or loss of memory.
Doctors remove the tumor and the patient is recovering.
