Aggressive periosteal reaction

Aggressive periosteal reaction
-This type of periostitis is multilayered, lamellated or demonstrates bone formation perpendicular to the cortical bone.
-It may be spiculated and interrupted - sometimes there is a Codman's triangle.
-A Codman's triangle refers to an elevation of the periosteum away from the cortex, forming an angle where the elevated periosteum and bone come together.
-In aggressive periostitis the periosteum does not have time to consolidate.
