296. What is the radiographic feature of tuberculosis of bone?
The initial radiographic finding of bone TB is osteoporosis, focally or diffusely involving the affected region. As the disease progresses, radiography may reveal lytic areas, commonly described as a "moth-eaten" appearance, due to the granulomatous destruction of bony trabeculae (Dx).
Other characteristic findings include a 'cold abscess' wherein there is formation of a periosteal reaction due to the spread of the infection to the soft tissues. One may also see peri-articular osteopenia, joint space narrowing, and juxta-articular cortical erosions in affected joints (Dx).
For late-stage disease, sequestra (dead, devascularized bone) and involucrum (new bone formation) may be observed. The Pott's disease (TB of the spine) can present as vertebral body collapse, commonly described as a 'gibbus deformity' (Dx).
