The extensive mucosal inflammatory changes and air fluid level within the sinus represent features of acute sinusitis
. You may need to consult and ENT specialist
to evaluate the sinuses
, especially you have any symptoms of sinusitis (eg: headache, pain over the face, stuffed or runny nose, etc). You probably do not require a CT scan unless your specialist asks for one.
The FLAIR hyperintensities in white matter
are non-specific. The description fits that of Fazekas Grade 1 changes which are of no significance or worry, especially if you are above 40-50 years of age. However, if they worsen on follow up MRI, especially in young patients (less than 40 years), it maybe an indicator for predisposition to development of dementia
early in life.
Hope this helps,
