Dude gets Brainworm from Frog Meat on his Eye

Then this happened:

A man who went to see his doctor after suffering headaches and experiencing strange smells was found to have been living for more than four years with a rare parasitic worm in his brain. […] Doctors were left baffled after spotting strange ring-like patterns moving 5cm through his brain tissue in a series of scans taken over four years. […] It is not known how he first became infected, but one source of infection is the use of frog poultice, a traditional Chinese remedy where raw frog meat is used to calm sore eyes.
