Parkinsonism, first time diagnosis. There is no evidence of intracranial hemorrhage, mass, or infarct. There is a 4 mm right choroid fissure cyst. The brain brain parenchyma otherwise appears unremarkable with minimal scattered foci of cerebral white matter T2 hyperintensity that may be related to chronic microangiopathy. Aside from possible blurring of the substantia nigrosome susceptibility signal, the brainstem and cerebellum appear to be grossly unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is a small right maxillary sinus retention cyst. There are bilateral lens implants.
Possible blurring of the substantia nigrosome susceptibility signal may be a manifestation of Parkinson disease. Otherwise, no evidence of intracranial mass, acute infract, or hemorrhage.
