Abstract

68Ga–prostate-specific membrane antigen (PSMA) ligand is a well-known tracer used in prostate cancer. Nevertheless, there are reports of unusual 68Ga-PSMA uptake in variety of benign lesions. We report a case of prostate cancer in which 68Ga-PSMA PET/CT revealed tracer avidity in the enhancing walls of cystic lesions in the brain consistent with the features of neurocysticercosis. The uptake of 68Ga-PSMA in neurocysticercosis is not known and may be attributed to angiogenesis occurring at the periphery of these lesions.
