Overview
On CT scan, osteomas demonstrate a well circumscribed mass of variable density, varying from very dense (similar in density to normal cortical bone) to less dense with a ground-glass appearance.[1]
CT
CT scan findings include:
- Well-circumscribed mass of variable density
- Ground-glass appearance
- Exophytical mass growing out of a sinus.
