Usefulness of f-18 FDG PET/CT in subcutaneous panniculitis-like t cell lymphoma: disease extent and treatment response evaluation


Zitieren

Background. Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare form of cutaneous lymphomas, accounting for less than 1% of cases of non-Hodgkin’s lymphoma. Fluorine-18 fluorodeoxyglucose (F-18 FDG) positronemission tomography/computed tomography (PET/CT) findings of SPTCL before and after treatment were rarely reported.

Case report. We report a case of SPTCL in which F-18 FDG PET/CT showed increased FDG accumulations in numerous subcutaneous nodules without extracutaneous disease. Contrast-enhanced CT during F-18 FDG PET/CT showed multiple minimally enhancing nodules with an infiltrative pattern in the subcutaneous layer throughout the body. Follow-up F-18 FDG PET/CT after three cycles of CHOP chemotherapy showed a complete metabolic remission of the lesions.

Conclusions. F-18 FDG PET/CT is suggested to be useful in assessing the disease activity, extent and treatment response in SPTCL.
