a-c Presurgical T1-weighted MR images showed a large, lobulated, and ill-defined 7.8 cm × 5.3 cm × 4.0 cm mass with inhomogeneous enhancement in the right temporal lobe (red arrows). The involvement of right lateral ventricular was also observed. d-f Follow-up postcontrast MR and (g-i) brain FDG PET /CT images indicated the postoperative changes without any signs of local recurrence at the resection cavity. (j) Whole-body FDG PET/CT anteroposterior 3-dimensional maximum intensity projection (3D-MIP) image showed a focal abnormal FDG-avid lesion in the cervical region without any other positive findings in the body (green arrow). (k-p) The selected sagittal and transaxial views of PET/CT images demonstrated a solitary intense FDG-avid osteolytic lesion associate with a compression fracture in the 4th cervical vertebral body (blue arrows). (o-p) Transaxial view of PET/CT images showed (blue arrow) increased FDG-uptake in the periphery of the mass with a photopenic center, the so-called “doughnut” sign
