From your description, you can draw the following conclusions:
1, multiple lacunar cerebral infarction and ischemic foci in bilateral basal ganglia and radiation coronal region, with some lesions softening;
2. Mild brain atrophy (some people like to use the word senile brain);
3, double maxillary sinus cyst, double ethmoid sinus chronic inflammation.
The first one is about the brain, which usually appears in the small blood vessels caused by cerebral arteriosclerosis. If you are worried, you can do a magnetic resonance angiography (MRA) to see if there are any lesions in the intracranial vessels.
Most people over 60 years old have multiple small lacunar infarction and ischemia. If you have obvious symptoms, you need to see a neurologist.
Maxillary sinus and ethmoid sinus are both paranasal sinuses, which have nothing to do with the brain. You can see an otolaryngologist.
