A large mass is seen arising from the lateral side of the left kidney on early 5-minutes blood pool images. No abnormal radiotracer accumulation/uptake is seen in the neck either on the initial blood pool or on the 3 hours delayed phase images. Normal symmetrical distribution of the radiotracer throughout the axial and appendicular skeleton noted on 3 hours delayed whole-body images. These bone scan findings in correlation with the previous x-ray & MRI scan findings are suggestive of an aggressive osteolytic lesion (likely solitary metastasis) involving the 5th cervical vertebra (showing no radiotracer uptake), with a high suspicion of a primary lesion in the left kidney.
