Figure 1: In pretreatment maximum intensity projection (a), axial CT (b), PET (c) and Fused (d) images intense 18F-FDG uptake (SUVmax: 9.8) was seen in primary tumor located in the proximal femur. Additionally pathological uptake was detected in right external iliac lymph nodes. (SUVmax:4.2). After treatment dramatical decrease in SUV of primary tumor (SUVmax: 3.7) and (e) absence of uptake in external iliac lymph nodes was confirmed.
