Hello
Hyperintense foci in white matter on MRI may be due to many reasons like ischemic changes,
demyelination,gliosis,post traumatic sequel,lyme's disease etc.
You need monitoring of conditions that leads to ischemic changes like hypertension,altered
lipid profile,
diabetes mellitus so that further progression of disease can be halted.
Demyelinating disease is associated with many clinical findings and lesions are found in typical sites.
You need investigations like routine hemogram,RBS,LFT,RFT,Lipid profile,ultrasound of abdomen.
Treatment depend upon findings.
Follow up MRI can be done to rule out demyelinating disease.
You also need clinical correlation.
Get well soon.
Take Care
