Multi-infarct progressive supranuclear palsy--case report.

A patient with supranuclear upward gaze palsy, pseudobulbar palsy, dementia, asymmetrical pyramidal signs, and atypical parkinsonism that developed after recurrent strokes was reported. The clinical features closely resembled idiopathic progressive supranuclear palsy (PSP). Computerised tomography of the brain showed, in addition to dilated third ventricle and prominent quadrigeminal plate and ambient cisterns, multiple infarcts at the thalamus, striatum, frontal subcortex and corona radiata. Multi-infarct PSP (MI-PSP) was thought to be the most likely diagnosis rather than coincidental idiopathic PSP with recurrent cerebral infarcts.
