Anaplastic Oligodendroglioma Found as an Incidental Photopenic Lesion on 18F-FP-CIT PET/CT Image

18F-FP-CIT PET is a useful modality for imaging dopamine transporters. It has excellent resolution compared with 123I-beta-CIT SPECT and is widely used clinically for the evaluation of Parkinson disease. In general, the main focus of 18F-FP-CIT PET imaging is the basal ganglia, and it is important to observe whether 18F-FP-CIT uptake is normal in the putamen and caudate nuclei. However, abnormal findings may be seen in other brain regions besides the basal ganglia. Here, we present a case of anaplastic oligodendroglioma, a high-grade tumor, which was found as an incidental photopenic lesion on 18F-FP-CIT PET/CT.
