Bone infarction/avascular necrosis can have increased FDG activity, likely from peri-infarct inflammation. This hasn't been very well studied in the literature and can sometimes result in a false-positive interpretation in the evaluation of metastatic disease. The image above shows mild FDG activity in the left femoral head, corresponding to avascular necrosis seen on the coronal T1-weighted image.
