Rosemary Alvarez went to the doctor because she had numbness in her arms and blurred vision. An MRI revealed something unusual deep in her brain stem, so doctors immediately sent her to surgery.
But they didn't find the tumor they expected - instead, they found ... a worm!
Doctors removed the worm and don't believe Alvarez will have any lingering health problems. No one knows exactly where she picked up the worm –- doctors said worms can come from eating undercooked pork or spread by people who don’t wash their hands after using the bathroom, according to the report.
