The F18-FDG-PET/CT study showed several areas of pathological lymph-node uptake in the upper mediastinum (Fig. 1).
14-year-old girl with nonossifying fibroma. Lucent lesion is noted in the distal right tibia on sagittally reformatted CT (left). Increased uptake is noted in this lesion on coronal F18-FDG PET (middle) and F18-FDG PET/CT fusion image (right).

The PET scan of the lower limbs showed a right tibial uptake (Fig. 2).
14-year-old girl with nonossifying fibroma. AP radiograph of both tibias, showing an eccentric, lucent lesion in the distal right tibia with a well-demarcated, sclerotic border, consistent with a nonossifying fibroma.

Radiography of the tibias revealed a lucent lesion, with findings consistent with nonossifying fibroma (Fig. 3).
14-year-old girl with nonossifying fibroma. Coronally reformatted CT (left), coronal F18-FDG PET (middle), and F18-FDG PET/CT fusion image (right). The lymphadenopathy noted in Figure 1 has completely resolved.

The evaluation at the end of treatment indicated complete lymphoma remission (Fig. 4).
14-year-old girl with nonossifying fibroma. Lucent lesion (left) is noted in the distal right tibia on coronally reformatted CT. Increased uptake is again noted in this lesion on coronal F18-FDG PET (middle) and F18-FDG PET/CT fusion image (right).
