Overview
Other imaging studies for ossifying fibroma include bone scan, which demonstrates mild hyperemia and moderate bone uptake during healing. However, in general they are negative.
Other Imaging Findings
Bone Scan
Ossifying Fibroma
Appearance of ossifying fibroma depends on the phase of the lesion. In general they are negative; however, mild hyperaemia and moderate bone uptake are present during healing. If extensive uptake or hyperaemia are present, then an alternative diagnosis or superimposed fracture should be considered.
Non ossifying fibroma
They are metabolically active on F18-FDG-PET images.That activity, probably is independent of lesion size, varies among patients and over time, as indicated by their F18-FDG uptake on PET. [1][2][3]
Chondromyxoid Fibroma
- On bone scans, the scintigraphic "doughnut sign" has been described in chondromyxoid fibroma. However, this is very nonspecific and can be seen in many other bone lesions.[4][5][6]
- On FDG-PET scan it showed increased accumulation of fluorodeoxyglucose.
