Patient 14 presented with HCC. On the WBS (a), there were multiple areas of abnormal ^99mTc-MDP uptake seen in the bilateral ribs and thoracic vertebra, which may mimic multiple bone metastasise. Axial CT (b), SPECT (c), and hybrid SPECT/spiral CT imaging (d) depicted increasing ^99mTc-MDP uptake corresponding to an expansile and lytic lesion with GGO in the lesion of bilateral ribs and thoracic vertebra. During the 2-year follow-up, no difference was detected in the WBS and CT image. The diagnosis of FD was established by a combined assessment of clinical and radiologic follow-up
