Multiple system atrophy and progressive supranuclear palsy cause tremor, movement disorders and cognitive impairment, are classified as Parkinson-plussyndrome. Magnetic resonance imaging has proved to be a useful investigation in distinguishing benign tremulous Parkinson’s disease from atypical tremor syndromes. In this article, we used two case vignettes to illustrate how MR imaging findings can assist in the diagnosis of tremor and various other movement disorders and can change the treatment in some cases. MRI showedselective atrophy of midbrain in progressive supranuclear palsy giving ‘hummingbird’ appearance and distinctive patterns of atrophy of brainstem and cerebellumwith signal changes in pons such as ‘hot cross bun’ in multiple system atrophy-cerebellar subtype. Thus, neuroimaging gives insight into the pathophysiology of tremor indicating the involvement of the brainstem and cerebellumas the most consistent finding in patients presenting with parkinson-plus-syndrome.
