In a shocking case, a California man suffering from violent headaches was found to have a tapeworm larvae lodged in his brain. Doctors said, "The pupal parasite burrowed in the brain of Luis Ortiz, 26, a student in Sacramento, came close to taking his life."
Neurosurgeon Dr. Soren Singel said, "The tapeworm was forming in a cyst that blocked the flow of water to chambers in Ortiz's brain, like a cork in a bottle."
Ortiz, who had gone to the hospital emergency room complaining of terrible headaches and nausea, eventually slipped into a coma, and required emergency surgery to remove the tapeworm larvae. On recovery Ortiz said, "I was shocked. I just couldn't believe something like that would happen to me. I didn't know there was a parasite in my head trying to ruin my life."
