Incidence of exclusive extrapelvic skeletal metastasis in prostate carcinoma on bone scintigraphy

Figure 2 A 66-year-old male with carcinoma of the prostate and serum prostate-specific antigen of 23. 3 ng/mL. A: Staging with whole body bone scintigraphy show focal areas of increased tracer uptake involving the right 6^th rib; B: Axial computed tomography (CT) and fused single photon emission computed tomography-CT images show tracer localization to the right 6^th rib anteriorly with a fracture line (arrow). The uptake was thus secondary to rib fracture post traumatic. There was no other abnormal uptake anywhere in the bones on whole body study.
