Although his joints showed no redness, swelling or tenderness, he had a limited range of motion of his hip and shoulder joints, suggesting a diagnosis of polymyalgia rheumatica (PMR). However, his relatively young age and subacute course along with the absence of morning stiffness made the diagnosis uncertain. We performed positron emission tomography\/CT, which revealed 18F-fluorodeoxyglucose uptake in bilateral upper and lower joints, consistent with PMR. There was also uptake by a sacral tumour, suggesting a diagnosis of paraneoplastic syndrome. Immunoglobulin A-\u03ba type M protein was detected in serum and bone marrow aspiration\/biopsy identified diffuse proliferation of atypical plasma cells, confirming a diagnosis of multiple myeloma. The patient received chemotherapy, which alleviated his limb pain, and achieved stringent complete remission after autologous peripheral blood stem cell transplantation.<\/jats:p>","DOI":"10.1136\/bcr-2013-203326","type":"journal-article","created":{"date-parts":[[2014,4,9]],"date-time":"2014-04-09T06:28:40Z","timestamp":1397024920000},"page":"bcr2013203326","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Positron
