A woman in Indiana underwent a non-invasive keyhole surgery to have her brain tumor removed, except, it wasn't a brain tumor at all. It was in fact, the woman's embryonic twin lodged on her brain. It had teeth, hair, and bones.

This story is way too bizarre to write. Watch the video below:


Yamini Karanam, 26, was unaware of what was happening in her head until she underwent a procedure designed to reach deep into the brain to extract the tumor. After waking up from the surgery, Karanam was surprised to learn of the “teratoma” — her embryonic twin, a rarity in modern medicine, complete with bone, hair and teeth.


Karanam realized last September that something wasn’t registering in her mind. The Indiana University Ph.D. student was experiencing trouble comprehending things she read.


“Problems with reading comprehension, listening comprehension. If a couple people were talking in a room, I wouldn’t understand what was happening,” Karanam said.


…Her own research led her to Dr. Hrayr Shahinian at the Skullbase Institute in Los Angeles. Shahinian developed a minimally-invasive way of reaching deep into the brain to extract tumors.
Karanam awoke to learn what was causing her all that trouble in Indiana. She lightheartedly called the tumor her “evil twin sister who’s been torturing me for the past 26 years.”


“This is my second one, and I’ve probably taken out 7,000 or 8,000 brain tumors,” Shahinian said.
Shahinian said his fear was that tumor may be cancerous. Pathologists, though, determined that not to be the case and Karanam is expected to make a full recovery in only three weeks.
