Embryonic twin discovered in a woman’s brain hailing from Hyderabad….

An Indian computer science PhD student from Hyderabad underwent brain surgery to find what she jokingly called her “evil twin sister who’s been torturing me for the past 26 years”. Doctors who performed brain surgery on Yamini Karanam, 26, in Los Angeles were shocked to find that instead of a tumour, she had an embryonic twin in her head.

Karanam, who was studying at Indiana University, was unaware of what was happening in her head until she underwent a procedure designed to reach deep into the brain to extract the tumour.

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.

“This is my second one, and I’ve probably taken out 7,000 or 8,000 brain tumours,” said Dr. Hrayr Shahinian at the Skull base Institute in Los Angeles, who performed the operation.

It was only last September that Karanam realised something wasn’t registering in her mind as she was experiencing trouble comprehending things she read. The Indiana University Ph.D. student was having trouble grasping things she was reading and understanding what was going on when more than one person was speaking at a time.

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

Realizing that something was not right, Karanam sought out several different doctors in hopes of obtaining a diagnosis. However, it became more frustrating for her when none of the doctors could agree on what was causing her problem.

Her own research led her to Shahinian who developed a minimally-invasive way of reaching deep into the brain to extract tumours.

“Unlike traditional brain surgery where you open the skull and use metal retractors and you bring a microscope to see in the depths of the brain, what we’re doing is keyhole surgery,” he was quoted as saying.

The method uses fibre-optic technology with digital imagery. A half-inch incision into the brain allows for an endoscope to reach in and slowly and very delicately chisel away at the tumour.

Shahinian said before he invented his technique, the only option to remove this type of tumour would have been surgery that included removing half of the skull.
