The man with a hole in his brain
Scans reveal a fluid-filled cavity in the brain of a normal man
Three years ago, a 44-year-old man was admitted to hospital in Marseille, France, complaining of weakness in his left leg. He had no idea what doctors would find to be the source of the problem: a huge pocket of fluid where most of his brain ought to be.

This case is certainly not unique. There was a BBC Panorama programme, circa 1978, about a bunch of children who had drainage valves installed to counter hydrocephalis in the early 1960s. With the advent of CAT scans, they were re-examined. The brightest of them was reading maths at Oxford, and had 10% of normal brain volume, just like the guy in the article. His visual centres got reused for doing sums when his eyes were closed!

I recall seeing a similar, but perhaps even more striking story on the Annenberg Channel: http://www.learner.org/vod/vod_window.html?pid=1575 .
I am curious about what experts say about these reports.

The Anneberg Channel video was very interesting. Timestamps on the UK CAT scans are in 1980, matching the mother's smock dress, and the era of the Panorama programme. The HP inkjet printer and mixed floppy drives in the US case suggest late 1980s.
It looks like this phenomenon was discovered 30 years ago, explored for 10 years, and then forgotten! I've seen other cases which suggest that the focus on administration and grant cycles has displaced the pursuit of knowledge, such that science is currently moving backwards.
