F1
In her dynamic MRI (Siemens, Germany, T2-weighted with Gadolinium enhancement), a contrast-enhanced tumor in the cerebello-pontine (CP) angle was found which was compatible with a meningioma (Figure 1). 
. Reconstructed 99mTc-TRODAT images which showed decreased uptake in the basal ganglia

Reconstructed SPECT images showed decreased radiotracer uptake in the left putamen compatible with idiopathic Parkinson disease (Figure 2). 
Reconstructed 99mTc-TRODAT images as well as the corresponding MRI (T2-weighted) which show the tracer uptake in the meningioma (MRI and SPECT images both were presented parallel to the orbito-meatal line).

Tumor to cerebellum count ratio was 7.8 on reconstructed SPECT images (Figure 3).
