The incidental suggestive meningioma presenting as high 18F FP-CIT uptake on PET/CT study.

A 76-year-old woman with about a 13-month history of bradykinesia, gait disturbance and resting tremor of right upper extremity was referred to Nuclear Medicine Department. A PET-CT with 229 MBq of F FP-CIT was performed to diagnose suspected early Parkinson's disease (PD). The PET-CT showed a mass lesion with highly intense focal dopamine transporter uptake in the right frontal lobe. A subsequent brain magnetic resonance image also showed a mass in the right frontal lobe demonstrating homogeneous enhancement and extensive surrounding edema, highly suggestive of a brain tumor.
