Clinical usefulness of FDG PET/CT in the detection of unusual central nervous system infections

• Two unusual CNS infection cases were successfully detected by FDG PET/CT.
• FDG PET/CT may have implications for the comprehensive assessment.
• Exploitation of FDG PET/CT for detecting rare CNS infections seems justified.

We report two unusual cases of suppurative meningomyelitis and ventriculitis which were successfully detected by FDG PET/CT. The extent of disease and response to treatment were well-delineated. Our data suggest that FDG PET/CT may be clinically useful in patients with rare infections of the central nervous system.
