Male, 75 years old, with essential tremor. DBS implantation scheduled. Scattered small foci of T2 hyperintensity are evident in the subcortical and periventricular white matter. Prominence of the sulci is compatible with some degree of parenchymal volume loss. A 6 x 5 mm extra-axial enhancing nodule is evident along the right posterior planum sphenoidale. No other enhancing lesions are seen. The ventricles are normal in size and configuration. No pathologic fluid collections are seen.
1.Scattered small white matter lesions are nonspecific but may reflect sequelae of microvascular ischemic disease.2.Some degree of parenchymal volume loss is suspected.3.An incidental small extra-axial mass presumed to represent a meningioma is evident along the posterior right planum sphenoidale.
