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

Figure 1 A 74-year-old male, with a newly diagnosed case of carcinoma of the prostate [Gleason’s Score 7 (4 + 3)] with serum prostate-specific antigen level 491 ng/mL and underwent whole body bone scintigraphy. A: ^99mTc methylene diphosphonate Whole body planar images show focal increased tracer uptake involving the cervical and lumbar vertebrae (arrow) raising the suspicion of metastatic disease; B: Axial computed tomography (CT) and fused single photon emission computed tomography (SPECT)-CT images show tracer localization to sclerotic lesion involving L3 vertebrae suggestive of metastatic disease. No metastatic disease was seen in pelvic bones on SPECT-CT.
