Figure 1: a) MDP bone scan of a 65 year old male post sternotomy. Bone scan images show linear increased tracer uptake in entire sternum with cold defects in lower body and xiphisternum. b) Gallium images show incongruent increased Gallium uptake in localised collection at manubrium (thick arrow) with abnormal Gallium uptake along sinus tracts in right lower anterior costochondral junctions and along 5th anterior ribs bilaterally (thin arrows).
