Yadira Rostro first started to notice bad headaches nine months ago and finally sought medical help after they continued to get worse.

It is believed the 31-year-old picked up the tapeworms on a trip to Mexico two years ago.

They are common in food contaminated with fecal matter but pass through most people in a few days.

Unfortunately for Yadira, they got into her bloodstream and then her brain.

With her permission, Methodist Dallas Medical Center shared video of doctors extracting the larvae earlier this month.

Neurosurgeon, Richard Meyrat explained:

"They looked a little bit like eggs, and they have a clear sac," he said. "And inside it, a small tapeworm."
