75 years, Male, right-sided weakness, evaluate for stroke. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. There is mild supra and infratentorial parenchymal volume loss, commensurate with patient's age. Unchanged prominence of the extra-axial CSF spaces along the superior cerebellar surfaces which may be related to underlying parenchymal volume loss or represent small chronic subdural effusions without significant mass effect. Brain parenchyma is otherwise unremarkable for age. Major flow-voids are preserved.Patchy opacification of the mastoid air cells is again seen, right worse than left. Diffuse opacification of the right frontal sinus is again seen. There is also diffuse opacification of the bilateral anterior and posterior ethmoid air cells, which is slightly worse since prior. There is mild bilateral maxillary sinus mucosal thickening. There is also mucosal thickening in the left sphenoid sinus which is also similar to prior. Evidence of left hard palate resection.
1. No evidence of acute infarct, hemorrhage, or intracranial mass effect.2. Slight worsening of paranasal sinus opacification compared to 2/25/2016.
