Is the picture of the CT scan real or just an illustration? Because I would assume that even if the woman doesn't have a cerebellum the brain should expand to occupy that space.
The article indicates it's the actual scan and says the space "was filled with cerebrospinal fluid, which cushions the brain and provides defence against disease."
Don't read the article provided too carefully. The image isn't a CT and has been dumbed down from the source. The image is an MR not a CT, and the image below is some sort of made up composite image. Original source with proper images: http://brain.oxfordjournals.org/content/early/2014/08/22/bra...
> The space where it should be was empty of tissue. Instead it was filled with cerebrospinal fluid, which cushions the brain and provides defence against disease.
Sorry, you are right. I only skimmed trough the article. It probably took me longer to write the comment that what it would have taken me to read the whole article.
