Abstract:
We report the F-FDG PET/CT findings of an etanercept-induced sarcoidosis in a patient with rheumatoid arthritis. A 68-year-old woman with rheumatoid arthritis who had been treated with etanercept and methotrexate showed multiple lung nodules and hilar lymph node swellings on CT. She underwent FDG PET/CT for cancer screening. Intense FDG uptakes were found in the multiple lung nodules, bilateral hilar lymph nodes, a periurethral masslike lesion, and cranial meningeal nodules. A histopathological examination revealed epithelioid granuloma with multinucleated giant cells, which was compatible with sarcoidosis.
