18F-Choline PET/CT Detected Skull Base Paraganglioma.

We present a case of a right skull base paraganglioma detected using F-choline PET/CT in a 63-year-old man. The F-choline PET/CT scan was performed to assess a known prostate cancer. In addition, the scan demonstrated a mildly choline-avid (SUVmax, 3.8) tumor within the carotid sheath of the right skull base, extending through the jugular foramen to the cerebellomedullary and cerebellopontine angles. F-choline may provide a superior alternative to FDG in imaging paragangliomas of the skull base because, unlike FDG, there is no significant F-choline uptake in the adjacent brain.
