Prostate-Specific Membrane Antigen-Avid Meningioma Detected in 68Ga-Prostate-Specific Membrane Antigen PET/CT.

A 64-year-old man with recently diagnosed prostate adenocarcinoma with a total prostate-specific antigen level of 3.32 ng/mL and Gleason score 4 (3 + 4) was referred for Ga-prostate-specific membrane antigen PET/CT scan for pretreatment staging. Prostate-specific membrane antigen-avid lesion was noted in the right lobe of the prostate gland, corresponding to the known primary lesion. Note was made of another prostate-specific membrane antigen-avid lesion in the right parietal lobe of brain, likely meningioma. MRI scan performed later confirmed the brain lesion to be meningioma.
