Thank you for posting your query.
The first finding- hyperintensity in the subcortical white matter- could represent an ischemia
(decreased blood flow to brain). Also, it is a common finding in migraine
The second finding represents a sinus infection
Both are minor findings and are not of any concern. However, I would advise you to discuss these findings with your doctor.
