Bone scintigraphy is routinely performed to identify bone and joint abnormalities in patients with low back pain. Urinary contamination by radiotracer excreted through the renal route may complicate scan interpretation, especially when localized to the symptomatic anatomical region. We present such a case where urinary contamination simulating a bony abnormality on the planar image was clearly identified only on SPECT.
