doesn't help with the coup contra-coup of the brain rattling in the CSF

I can't remember the name, but there's a condition where one half of the brain dies, and the remove an entire hemisphere, which you can survive. That big hole fills with cerebral spinal fluid (CSF) too, so the brain doesn't bounce around in there.

So what's left? A person missing 75% of brain mass in a vegetative state?


I can't speak for this case, but I had a benign tumor the size of a kiwi fruit removed from the left side of my brain 7 years ago, and I'm fine (albeit on anti-seizure meds for probably the rest of my life). How damaging the tumor or cyst is to the brain I think has to do with how quickly it grows,and surely the location; it's probably generally less serious if the tumor/cyst growth occurs on the "outside" of the brain vs inside it.

The brain gets compressed to accommodate the growth, but the brain itself in some/many? cases isn't considered damaged. In my case the compression of the brain finally got to the point where I had a grand-mal seizure -- that was my first clue anything was wrong. After my surgery I basically had a dented brain, but it "bounced back" to its former size over a few months.

My guess is that this person had a similar experience, that they had no clue it was there for quite a while, even though their brain was getting progressively more squashed and they might have been having weird symptoms, like motor or behavioral oddities, or seizures, etc. Depends on the area of the brain that's being stimulated from the compression.

Oh, here's more info on the video from the link provided by Hawkinson above:
_________________

The video below uses saline to gradually "float" the cyst out of the brain. The neurosurgeon gently squirts small volumes of saline into the space around and behind the cyst until it neatly plops into the surgical pan, intact. The patient, a 16 year old girl, fully recovered.

- And, what happens to the hole the cyst left in the brain?

"The empty space initially gets filled up by the fluid which covers thr brain called CSF, then the brain which was compressed by the cyst expands to normal state filling up the space."
