UPPER EAST SIDE, Manhattan (WABC) -- "The good news is, I don't have cancer."
That is also surprising news, because doctors at Mount Sinai Hospital thought just the opposite - until last September, when neurosurgeons opened up Rachel Palma's skull.
They fully expected to find a marble-size malignant brain tumor. Instead, they found a parasite.
"We were, like, overjoyed," said Dr. Jonathan Rasouli. "We were, like, cheering and clapping. We were so happy.... When we got in there and saw that it was a tapeworm, we were like, 'YES!' We were so happy!"
It was January of last year when strange things started happening to the 42-year-old from Middletown.
She'd suddenly drop her coffee mug. She couldn't remember words. She tried calling deceased relatives.
After countless doctor visits and numerous brain scans, specialists at Mount Sinai found the problem and developed a plan of attack: a three-hour surgery.
They showed us images of the brain scan and described what they saw: "This is the lesion, and you can see how it enhances - it's very bright white here. And inside of it, it's dark. And you see the same thing here."
The big mystery to this story is how the parasite got there. The patient never traveled outside the United States. She doesn't recall eating uncooked meat. And frankly, she's given up trying to find an answer.
"I stopped asking questions and started celebrating and making the most out of life," she said, "because in an instant it can be taken away."
Doctors say had they known it was a tapeworm and not a tumor causing all the problems, perhaps a heavy dose of antibiotics would have served as a remedy.
But that doesn't phase Rachel Palma.
"There is not a doubt in my mind that they saved my life," she said. "And they gave me my life back."
A life, that is, temporarily hijacked by a parasite.
