A CT scan performed to search for malignancy showed a 5 cm heterogeneously enhancing solid mass in the lower pole of the left kidney compatible with a renal neoplasm (Fig. 1).
67-year-old man with renal cell carcinoma with paraneoplastic manifestations. Composite PET image (sequence: coronal, sagittal, axial and volumetric images) shows increased F-18 FDG uptake at the left iliac bone, left acetabulum and left ischium compatible with hypermetabolic osseous lesions (small arrows). The patient is status left nephrectomy with absent activity in the left renal fossa (arrowhead).

PET showed abnormal radiotracer uptake at the left iliac crest, acetabulum and ischium without corresponding bone lesions on concomitant transmission CT (Figure 2, Figure 3).
67-year-old man with renal cell carcinoma with paraneoplastic manifestations. Composite F-18 FDG PET/CT image of the left pelvis (image sequence: CT, PET, and fused PET/CT in coronal, sagittal and axial projections) shows abnormal radiotracer accumulation in the left iliac bone and left acetabulum suggestive of hypermetabolic bone lesions (arrows). The transmission CT of this composite image shows no obvious lesion to match the PET findings.
