Abstract
Although 18F-FDG is the dominant radiotracer for PET imaging of hematological malignancies, radiolabeled amino acids have also been investigated to improve image quality in areas of high 18F-FDG uptake such as the central nervous system. We present a case of a 57-year-old woman who underwent an 18F-FDOPA scan for primary CNS lymphoma, which demonstrated an unexpected false-positive uptake in the right frontal lobe, due to a developmental venous anomaly.
