First described in The Lancet in 2007, the case of the man with the missing brain has been puzzling scientists for almost 10 years.
The French man was 44 years old at the time the journal article came out, and although his identity was kept confidential, the researchers explained how he’d lived most of his life without realising anything was wrong with him.
He only went to the doctor complaining of mild weakness in his left leg, when brain scans revealed that his skull was mostly filled with fluid, leaving just a thin outer layer of actual brain tissue, with the internal part of his brain almost totally eroded away.
