Case Report: 18 F-FDG PET/CT for FUO Due to Whipple Disease Infection

Area of Science:

• Medical imaging
• Nuclear medicine
• Rheumatology

Background:

• A 60-year-old male presented with prolonged fever of unknown origin (FUO).
• The patient had a history of immunosuppressant and corticosteroid use for seronegative rheumatic disease, indicating an immunocompromised state.
• Symptoms included severe headache, characteristic facial skin lesions, abdominal pain, and myalgia.

Purpose of the Study:

• To investigate the potential infectious etiology of FUO in an immunocompromised patient.
• To evaluate the utility of 18F-FDG PET/CT in identifying the source of infection in complex clinical presentations.

Main Methods:

• The patient underwent a standard clinical workup for FUO.
• 18F-FDG PET/CT imaging was performed to localize potential infectious foci.

Main Results:

• The abstract does not contain specific results from the 18F-FDG PET/CT scan.
• The imaging was utilized as part of the diagnostic process for FUO.

Conclusions:

• 18F-FDG PET/CT is a valuable tool in the diagnostic armamentarium for fever of unknown origin, particularly in immunocompromised patients.
• Further investigation is warranted to determine the specific findings and clinical impact of the PET/CT scan in this case.
