26-year-old Yamini Karanam was diagnosed with a pineal brain tumor, but during the operation, doctors made a shocking discovery in her head. They found teratomas - bones, hair and teeth of an underdeveloped twin embryo.
It all started with the fact that the student sought medical help after pain in the head. Doctors at Indiana University found a tumor in her brain and announced the need for surgery.
However, their surprise knew no bounds when they discovered that they had mistaken for a tumor of the embryo of the girl's twin in its infancy, including its bones, hair and teeth, writes The Daily Mail.
Teratoma is a tumor that grows from the cells of the embryo. It develops even before a person is born, and the appearance of clinical manifestations is possible at any age. The name of the tumor comes from the Greek teratos - "monster" and oma - "tumor". This is explained by the fact that the reason for the development of the tumor is a violation of the normal development of the tissues of the embryo.
Mature teratomas, which are usually benign, are more common in women. Immature teratomas, which are usually cancerous, are more common in men. These formations can be found in the testes in men and in the ovaries in women, as well as in the brain, skull, nose, tongue, under the tongue, and in the neck.
