Correct answer: C — Ground-glass or orange-peel radiopacity with ill-defined borders blending into normal bone
Fibrous dysplasia presents radiographically with a characteristic ground-glass, orange-peel, or fingerprint-like mixed radiopacity. The lesion has ill-defined borders that blend gradually into surrounding normal bone (no distinct capsule or corticated margin). It causes painless, unilateral, progressive bony expansion. Monostotic (single bone) is more common than polyostotic. The involved bone cortex thins but usually remains intact. Root displacement without resorption is typical. No treatment is needed unless functional or cosmetic concerns arise.
