Conclusion
The non-ossifying fibroma is in most cases a radiological accidental finding and occurs mainly in children and adolescents. It is a benign connective tissue bone change, which heals spontaneously in most cases. Very rarely, a fracture may occur, but it can heal on its own.
If the area of the non-ossifying fibroma is very large, removal and filling with cancellous bone is recommended. Actually, there are no real differential diagnoses, i.e. other diseases that resemble the image of non-ossifying fibroma. If one is still not sure, an MRI can be used for further confirmation.
