Hi doctors, My father is 64 years old. He is a diabetic patient and had TB a decade ago. Recently he had to undergo a surgery in his head because there was a benign tumour in the liquid present between his brain and skull ( I don't know the medical term for it. This is how the doctor explained to us). We were checking his CT scan and there was something mentioned in the final impression that says "diffuse neuroparenchymal atrophy with more severe cerebellar atropy". Is this something serious? Should we be worried about this? Is this curable or treatable with medications..? Please let me know what can be done... I have attached a photo of the CT scan results for your perusal. Please help.
