Tapeworm inside brain for 4 years

A British man lived for four years with a rare tapeworm in his brain, scientists have revealed.

The 1cm-long parasite left the 50-year-old man in pain and with memory problems as it travelled 5cm from the right side of his brain to the left before it was removed by surgeons.

The rare worm was of a type never before found in the UK but it is believed that it can be caught by eating infected food or via a Chinese medical remedy for sore eyes that includes raw frog.
