In brief: Neurological finding
The combination of headache, fever and focal neurologic findings are highly suggestive of brain abscess.
Neurologic findings include trouble walking, speaking, eating and swallowing, severe memory issues, confusion, seizures and many other symptoms. Sinus infections are very common and brain abscesses extremely rare.

Brain MRI or head CT with contrast are also very helpful.

In brief: Both cause headache
The other major symptom of sinusitis is coughing.
Usually there is green or yellow nasal discharge & stuffy nose. The upper molars may ache. Fever is present only with acute sinusitis. The neurological symptoms of brain abscess may be subtle at first but will get progressively worse with time. The expanding abscess displaces the rest of the brain causes major neurological dysfunction. See ct scan.
