Whole body bone scan with 99Tc MDP of the patient. (a) Anterior and (b) posterior views, showing mildly increased tracer uptake in the lumbar vertebrae (black arrow) and intense, focal localization of the tracer in the lower pole of left kidney (red arrows).

Technitium methylene diphosphonate (99m Tc-MDP) bone scan was performed. The scan [Figures 1 and 2] showed mildly increased tracer uptake in lumbar vertebrae and focal accumulation of tracer in lower pole of the left kidney.
(a-b) Lateral and (c-d) oblique views clearly demonstrate the focal tracer uptake outside the skeletal structures in left kidney (arrows).

Technitium methylene diphosphonate (99m Tc-MDP) bone scan was performed. The scan [Figures 1 and 2] showed mildly increased tracer uptake in lumbar vertebrae and focal accumulation of tracer in lower pole of the left kidney.
(a) Coronal, (b) sagittal and (c) transaxial CT images; (d) coronal (e) sagittal and (f) transaxial SPECT images; (g) Coronal, (h) sagittal and (i) transaxial SPECT-CT images. These revealed focal tracer accumulation in the left renal calculus (white arrows). The calculus measured 8 x 8 mm in size. The CT attenuation factor was 1060 Hounsfield unit, compatible with that of a renal calculus.

Fusion imaging [Figure 3], using Single Photon Emission Computed Tomography along with X-ray Computed Tomography (SPECT-CT) of the lumbar spine was performed to characterize the vertebral tracer uptake.
