Typical radiographic characteristics of malignant or aggressive bone lesions and nonmalignant and nonaggressive bone lesions

Characteristic	Malignant or aggressive nonmalignant lesions*	Nonmalignant and nonaggressive lesions
Border	Poorly defined	Well-defined or sclerotic border Sharp zone of transition from normal to abnormal bone
Periosteal reaction	Often present (eg, spiculated, interrupted, wedge-shaped [ie, Codman triangle])^¶	Absent^¶
Cortical destruction	Cortical destruction is typical ("moth-eaten" or permeative pattern)	Cortical destruction is usually absent
Extension	Extends into the soft tissue	Confined by natural barriers (eg, growth plate, cortex) Does not extend into the soft tissue

* Aggressive nonmalignant bone lesions include aneurysmal bone cyst, chondroblastoma, chondromyxoid fibroma, and giant cell tumor.
¶ The absence of periosteal reaction does not exclude a malignant lesion.
