Which radiographic features may be present with osteomyelitis?

The radiographic signs of osteomyelitis reflect infection of bone and surrounding tissues. Early imaging may show soft tissue swelling from inflammation. As the infection evolves, the periosteum can lay down new bone around the diseased area, forming an involucrum, and dead bone fragments can become sequestra. A Brodie’s abscess is a localized subacute osteomyelitis in the metaphysis, typically appearing as a lucent area with a sclerotic rim, often with surrounding bone reaction. Together these features are characteristic of osteomyelitis on X-ray. The other options describe degenerative or traumatic changes (osteophytes with joint space narrowing; disc space narrowing; vertebral fracture with deformity) that are not typical radiographic patterns of osteomyelitis.
