68Ga-Prostate-Specific Membrane Antigen Expression in Neurocysticercosis Lesions in a Patient With Prostate Carcinoma.

Ga-prostate-specific membrane antigen (PSMA) ligand is a well-known tracer used in prostate cancer. Nevertheless, there are reports of unusual Ga-PSMA uptake in variety of benign lesions. We report a case of prostate cancer in which Ga-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 Ga-PSMA in neurocysticercosis is not known and may be attributed to angiogenesis occurring at the periphery of these lesions.
