Fig. 2

A 45-year-old male with benign GCTTS. The lesion was hypointense on T1WI (A, arrow) and mostly hypointense on T2WI in the T9 vertebra (B, arrows). Enhanced MRI scans revealed heterogeneous enhancement (C, arrows). Recurrence was suspected after surgery, and PET showed high 18F-FDG uptake in the vertebral body (D, arrow). The lesion was blurred on CT because of the interference from artefacts (E, arrow), but the fusion image clearly showed the high 18F-FDG-uptake lesion at the anterior edge of the T11 vertebra (F arrow)
