Resumo

A 68-year-old man in whom a prostate cancer biochemical recurrence was being investigated was referred for a full-body Ga-68-prostate-specific membrane antigen PET/CT. Focal uptake in a lesion on the choroid plexus projection was detected. Patient had no neurological complaints. A previous MRI performed 4 years ago showed the same lesion. According to the location and radiological and clinical characteristics, the diagnosis of meningioma was defined. The interpretation of prostate-specific membrane antigen PET/CT must take into account the low frequency of metastases in sites such as the central nervous system, and the possibility of intense uptake in lesions unrelated to prostate cancer.
