Thank you all for your input. My brother had his appointment with the neurosurgeon on Friday and he also said the cyst can not be causing the symptoms he has. At times he has very impaired motor function, headache etc., but they think its coming from elsewhere.

They want him to see a doctor in NYC or Toronto because what is going on is so unusual an debilitating. We are in PA, so either is a far drive, lol. We will see.

Take Care
