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.
