Maximum intensity projection image of fluorodeoxy glucose scan with fluorodeoxy glucose-avid lesion in the left humerus marked by a thick arrow, while the skull lesion cannot be appreciated due to high adjacent normal brain activity

There was evidence of a FDG-avid lytic-sclerotic lesion with destructive pattern in the mid-humerus and distal humerus with associated soft-tissue mass [Figures 1 and 2].
Coronal sections of computed tomography, positron emission tomography, and fused positron emission tomography/computed tomography images, respectively, showing an increased fluorodeoxy glucose uptake in lytic-sclerotic lesion of the left humerus

There was evidence of a FDG-avid lytic-sclerotic lesion with destructive pattern in the mid-humerus and distal humerus with associated soft-tissue mass [Figures 1 and 2].
Transaxial computed tomography and fused transaxial fluorodeoxy glucose scan showing fluorodeoxy glucose-avid lytic lesions. Due to increased fluorodeoxy glucose uptake in the normal brain parenchyma, the fluorodeoxy glucose uptake in the skull lesion cannot be well appreciated

Another poorly defined lytic lesion was seen in the high frontoparietal region of the skull vault with an associated soft-tissue mass extending into the scalp [Figure 3]. The lesion showed heterogeneously increased FDG uptake [Figure 3].
Maximum intensity projection positron emission tomography image of fluoroethyl tyrosine scan showing a single lesion in the skull marked with an arrow having increased fluoroethyl tyrosine uptake; however, no uptake in the left humerus is noted

FET PET-CT revealed no uptake of tracer in the lytic-sclerotic lesion of the humerus [Figure 4], but an increased uptake was noted in the lytic lesion of the skull [Figure 5].
Transaxial computed tomography and fused transaxial fluoroethyl tyrosine positron emission tomography-computed tomography scan showing an increased fluoroethyl tyrosine uptake in lytic lesion in the skull marked by an arrow
