A man in France shocked doctors after showing up to hospital with relatively ordinary symptoms (a weakness in his leg), however, after conducting several tests doctors would discover this man was anything but normal. It would turn out this man’s head was mostly empty as 90% of his brain was missing. This begged the question, how was this man able to function and lead a normal life?
The puzzling medical case was first published in The Lancet medical journal in 2007 but it still baffles people to this day. The man had been experiencing a weakness in one of his legs which is what prompted him to speak to doctors in the first place. According to CBC.ca, while testing the man, doctors discovered that instead of having a brain inside his skull, the 44-year-old man’s head was full of liquid with just a thin layer of brain tissue in his skull. The condition is known as hydrocephalus.
