Parkinson's disease [G20], Reason for Study: ^Reason: DBS protocol History: DBS protocol No evidence of acute hemorrhagic lesion.Since this scan does not include diffusion weighted image, acute ischemic stroke cannot be evaluated. However, there is no evidence of abnormal high signal intensity on T2 weighted image.Underlying brain shows mild brain atrophy, otherwise unremarkable. The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.Mucosal thickening and opacifications of bilateral maxillary sinuses, ethmoid sinuses, sphenoid sinus and frontal sinus indicating pansinusitis. There is tubular T2 high signal lesion in the right inferior nasal meatus extending toward nasopharynx which could represent nasal polyp, thus clinical examination or dedicated imaging can be considered if clinically warranted.
1. No evidence of acute hemorrhagic lesion.2. Minimal brain atrophy, otherwise unremarkable.
