Hello
Your findings suggests polycystic kidneys.These are developmental abnormalities and usually only need follow up ultrasound.
Findings also suggests ischemic foci in bilateral parietal region.
Ischemic changes generally occurs in conditions like hypertension,altered
lipid profile,
diabetes mellitus,vasculitis etc.These conditions damage small blood vessels and this leads to ischemia.
So,you need screening of these conditions.It includes proper clinical examination and investigations like routine hemogram,random blood sugar,liver function test,renal function test,lipid profile.
You may need to take few medicines after evaluation.
However other causes may be
demyelinating disease,
migraine headache,edema etc.These conditions should also be ruled out and you may need follow up MRI to see progression of lesions.
There is also an old infarct in right cerebellum.
There are also incidental
arachnoid cyst in bilateral temporal region.It generally doesn't require any treatment.
There are also age related atrophic changes in brain.
Get well soon.
Take Care
