A recent case study involving a 71-year-old male with renal carcinoma demonstrated the incidental detection of giant cell arteritis during 18F-FDG PET/CT imaging. The patient was administered 370 MBq of 18F-FDG for the scan. Increased tracer uptake was observed throughout the aorta, supporting the diagnosis of giant cell arteritis. These findings indicate the potential for PET/CT scans to identify significant co-morbidities, reinforcing the need to thoroughly interpret imaging data.
