We report a case of a patient with relapse of POEMS syndrome (peripheral neuropathy, organomegaly, endocrinopathy, monoclonal plasma proliferative disorder, skin changes) that occurred 6 years after an autologous peripheral blood stem cell transplantation. F-18 FDG PET/CT showed several hypermetabolic as well as nonhypermetabolic bone lesions. Based on these findings, the patient was referred for radiotherapy to the hypermetabolic bone lesions. After autologous peripheral blood stem cell transplantation, F-18 FDG PET/CT may play a pivotal role in detecting new bone lesions in patients with POEMS syndrome, which may be treated by a focalized radiotherapy and/or systemic therapy.
