Cerebellar Metastases From Prostate Cancer Detected by PET/CT with 18F-choline

A 76-year-old male, previously submitted to enucleation of renal-cell carcinoma (pT1) and prostatectomy for prostate cancer (Gleason score 3+5, pT3b pN0 pMx), was submitted to positron emission computed tomography (PET/CT) with 18F-choline for restaging due to raising levels of prostate specific antigen (PSA). PET/CT scan showed increased tracer incorporation corresponding to bone metastases in the left ischio-pubic ramus, also revealing 2 areas of increased tracer uptake in the cerebellum, subsequently confirmed by brain magnetic resonance imaging (MRI). The patient was urgently submitted to neurosurgery. Post-operative histology was positive for brain metastases from prostate cancer.
