MRI of nondegenerative “symptomatic” causes of parkinsonism. a Bilateral thalamic grade II glioma. Axial T2-weighted turbo spin echo MR image reveals two hyperintense mass lesions in the thalami. b Axial T2-weighted FLAIR MR image shows marked dilatation of the lateral ventricles exhibiting a ballooned shape and effacement of the cortical sulci. c Sagittal T1 spin echo MR image confirms the dilatation of the lateral ventricle and reveals dilatation of the cerebral aqueduct and fourth ventricle. Note the bowing of the corpus callosum and the effacement of the cortical sulci. Both cases in b and c images have normal pressure hydrocephalus. d Creutzfeldt-Jakob disease. Axial T2-weighted MR image shows symmetric hyperintensity of the putamen and head of caudate. e Axial T1-weighted spin echo and coronal T1-weighted gradient echo. f MR images show marked symmetric hyperintensity of the globus pallidus, putamen, and caudate [63]
