Including malignancy, various disease can show abnormal uptake in bone marrow.1,2) We report a case of non-specific inflammatory FDG uptake in bone marrow mimicking malignancy. A 35-year old woman with fever of unknown origin (FUO) underwent 18F-FDG PET/CT to find out fever focus and unknown malignancy. 18F-FDG was injected and imaged 1hr after injection with Discovery ST (GE, USA). 18F-FDG PET/CT whole body image showed abnormal uptake in lower extremities (Fig. 1). MRI and biopsy was also done in the sites of abnormal uptake. PET and MRI suspect malignancy (Fig. 2, 3), but biopsy result was non-specific inflammatory process (Fig. 4). The patient was improved her clinical condition after antibiotics therapy.
