Woman discovers her brain tumor is actually her embryonic twin
Indiana Ph.D. student Yamini Karanam got the surprise of her life last week when doctors found an embryonic tumor twin in her brain. Her problems started last fall when she couldn't concentrate or comprehend what was going on around her.
She went to doctor after doctor, but they couldn't agree on the problem.
"The neurologist would say the neurosurgeon is not being practical in your case," Karanam told NBC News. "And the neurosurgeon would say the neurologist is not being optimistic in your case. And I'm like, could someone be educated about this?"
She ultimately got help from a Los Angeles-based doctor who removed the tumor. Once Dr. Hrayr Shahinian at the Skullbase Institute removed the tumor he found that it was a twin with teeth, bone and hair — medically known as a teratoma. It's officially known as a type of tumor made of cysts that contain at least one layer of cells found in a growing baby.
"This is my second one, and I've probably taken out 7,000 or 8,000 brain tumors," Shahinian told NBC News of the rarity of such a tumor. They're baffling to the medical community, though some experts believe they're the product of twins that never develop and are absorbed into the remaining twin's body, according to The Washington Post, and they can develop anywhere, including the abdomen, chest and ovaries. Some can even have muscle and actually look like a fetus.
Doctors aren't sure if the teratoma found in Karanam's brain was actually her "evil twin," as she called it, but they do know it's benign and she'll recover in just a few weeks.
"I was stuck with it much longer than I thought," she told The Washington Post of her tumor. "It doesn't leave you much choice other than to deal with it the best you can."
