An Uncommon Presentation of Progressive Supranuclear Palsy Diagnosed on DaT Scan

Diagnosis of Parkinson's disease can be difficult in presence of atypical symptoms and signs. While the commonest reason of parkinsonism is idiopathic Parkinson's disease (PD), other disease entities that can mimic PD should be considered in the light of clinical history and examination findings. However, still some diagnostic dilemmas may exist which may need special investigative modalities. In recent years, advancements have been made to use single proton emission computed tomography (SPECT) scan to determine the cause of parkinsonian features. However, clinical use of this specialized tool is still not well-recognized. We have presented here a case of supranuclear palsy that was difficult to diagnose clinically and had appropriate final diagnosis with the help of dopamine transporters (DaT) scan.
