Abstract:
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.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
