NOF: typical presentation as an eccentric, multi-loculated subcortical lesion with a central lucency and a scalloped sclerotic margin.

NOF
-NOF is a benign well-defined, solitary lesion due to proliferation of fibrous tissue.
-It is the most common bone lesion.
-NOF is frequently a coincidental finding with or without a fracture.
-NOF usually has a sclerotic border and can be expansile.
-They regress spontaneously with gradual fill in.
-NOF may occur as a multifocal lesion. The radiographic appearance is almost always typical, and as such additional imaging and biopsy is not warranted.
Discriminators:
Must be under age 30.
No periostitis or pain.
