An Incidental Finding of Skull Hemangioma During 18F-FP CIT Brain PET/CT

摘要

F-18-FP CIT has been well established and used for the differential diagnosis of atypical parkinsonian disorders, including idiopathic Parkinson disease. A 54-year-old woman with a history of left hand and leg tremor underwent F-18-FP CIT PET/CT for the differentiation of parkinsonism. The F-18-FP CIT PET/CT incidentally showed focal dopamine transporter uptake in the right frontal bone. Brain MRI scan showed heterogeneous high signal intensity with enhancement in right frontal bone diploic space without cortical disruption, suggestive of cavernous hemangioma. Besides the nigrostriatal dopaminergic system, F-18-FP CIT PET/CT showed a skull tumor.
