On bone scintigraphy, most giant cell tumours demonstrate increased uptake on delayed images, especially around the periphery, with a central photopenic region (doughnut sign).
Increased blood pool activity is also seen, and can be seen in adjacent bones due to generalised regional hyperaemia (contiguous bone activity). Giant cell tumor of bone (GCTB) is generally considered to be a benign tumor occurring in the epiphyseal and metaphyseal regions of long bones with a locally aggressive profile.
