"Evil Twin" found in woman's brain

If one was to hear that they had an embryonic twin in their brain, they would not only be petrified but they would also act hysterically after receiving the news. However, that was not the case for Yamini Karanam, who reacted quite calmly after receiving this news.

Yamini Karanam (26), a PhD student from Indiana University seemed relieved that it was teratoma and not a brain tumour. The fact that it had teeth and hair didn't make her squirm.

Karanam had been having trouble with her speech and reading, but with the removal of the teratoma, her condition may improve.

Teratoma is a type of germ cell tumour that contain many different types of tissues. Sometimes, it can also contain mature elements such as hair, muscle and bone. Teratomas most often occur in the ovary, testis and the sacrococcygeal region (at the base of the tailbone) in children.

In an interview with NBC Los Angeles, she referred to the embryonic twin as the “evil twin sister who's been torturing me for the past 26 years.”
