My father (72 yrs) recently diagnosed with colloid cyst in third ventricle. He has all the symptoms like memory loss, drowsiness, vomiting.. Recently he is not even to walk as his legs and hands are shaking ( leg getting stiff) while standing. He is also a kidney patient with little high creatinine. He is under treatment under a nefrologist from last 10 yrs. But recently his condition has become worse as he is always in drowsiness, does not have the wish to speak or listen anything. If we treat colloid cyst, his problem will be resolved? (CT scan found cyst size is less) do you treat colloid cyst. Please tell me in details, expected cost of surgery, success chance of surgery, method of surgery (micro or open skull), chance of repeating cyst, and how many days to be admitted in hospital .
