Remarkable FDG Uptake in Numerous Granulomatous Panniculitis Lesions: A Case Report.

ABSTRACT: A 42-year-old woman with history of rheumatoid arthritis and erythema nodosum from 8 years ago, who was treated with CellCept and prednisolone, was admitted to the rheumatology service due to skin lesions in the upper and lower extremities. Skin excisional biopsy was performed, and the results suggested panniculitis. FDG PET/CT was performed for malignancy workup. The scan images revealed intensely increased FDG uptake in all numerous subcutaneous nodules. FDG uptake in the panniculitis lesion is rarely reported in the literature.
