Almost no brain

The picture to the left shows a large empty space where this man’s brain should be. The dark area occupying most of his head and labeled “LV” is fluid instead of brain. Amazingly, with just a little bit of gray matter on his inner skull, he has lived 44 years before anyone noticed his head is almost empty.

The man’s IQ is a somewhat low 75, but he has managed to lead a normal life and holds a job in France as a civil servant. More of the story is available here.
