Atypical Parkinson Syndrome Hiding a Meningioma

Clin Nucl Med. 2019 Dec;44(12):987-988. doi: 10.1097/RLU.0000000000002767.

Abstract

A 59-year-old man had developed within a few months walking disorders and rigidity of the left upper limb. I-FP-CIT SPECT/CT was performed in response to the suspicion of atypical parkinsonian syndrome. It showed an anomaly in presynaptic dopaminergic transmission on the right striatum and a voluminous expansive process on CT. MRI revealed an atypical meningioma. The patient had surgery for tumor removal. Later I-FP-CIT SPECT/CT showed normalization of presynaptic dopaminergic transmission on the right striatum.
