Hello
Periventricular and subcortical white matter T2 prolongation may be due to ischemic( decreased blood supply and oxygenation due to involvement of small blood vessels)changes in white matter of brain.
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.
Other findings related to brain are normal.
Findings also suggest mild sinusitis involving all sinuses.You may need ENT consultation.
Get well soon.
Take Care
