Progressive Supranuclear Palsy Misdiagnosed as Parkinson's Disease: A Case Report and Review of Literature

Because of its increasingly recognized clinical diversity, progressive supranuclear palsy (PSP) may be difficult to diagnose, particularly in resource-poor settings where the means of getting supportive tests is a huge challenge. This often results in underdiagnosis or misdiagnosis of PSP, most commonly as Parkinson's disease. The author reported a case of how brain magnetic resonance imaging (MRI) was used to arrive at the diagnosis of PSP in a man previously misdiagnosed as Parkinson's disease. Relevant literatures regarding the diagnostic utility of MRI in PSP were also reviewed.
