Right facial weakness. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are numerous foci of high T2 signal in the supratentorial and infratentorial white matter.

There is a nonspecific subcentimeter nodule in the right parietal scalp. The skull, orbits, and scalp soft tissues are otherwise unremarkable. There is diffuse paranasal sinus mucosal thickening and secretions, including air-fluid levels in the left maxillary sinus.
