Cerebellar Metastases from Prostate Cancer Detected by PET/CT with ¹⁸F-Choline

A 76-year-old male, previously submitted enucleation 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 raised levels of prostate-specific antigen. 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. The patient was urgently submitted to neurosurgery. Post-operative histology was positive for brain metastases from prostate cancer.
