Instead, radioactive urine collection in (atypically located) renal calyx was visualized [Figure 1].

SPECT/CT showed a strong activity enhancement in the 12th rib left in the SPECT as well as bone remodeling and distention in the CT (a pattern typical for a bone metastasis), and no urine collection in the kidney [Figure 2].

The focus left appeared to have a double origin: Urine collection in the left kidney and enhanced bony metabolism in the 11th rib (together with bone remodeling in the CT), which was interpreted as typical for bone metastasis [Figure 3].
