SUMMARY

3. X RAYS OF INFECTIONS OF BONES

4. OSTEOMYELITIS
Osteomyelitis refers to inflammation of bone that is almost always due to infection, typically bacterial.
Other non-pyogenic causes of osteomyelitis are discussed separately:
Tuberculous osteomyelitis
Skeletal syphilis
Fungal osteomyelitis

5. Osteomyelitis can occur at any age.
In those without specific risk factors, it is particularly common between the ages of 2-12 years of age and is more common in males (M:F of 3:1).

6. The diagnostic imaging of osteomyelitis can require the combination of diverse imaging techniques for an accurate diagnosis.
Conventional radiography should always be the first imaging modality to start with, as it provides an overview of the anatomy and the pathologic conditions of the bone and soft tissues of the region of interest.

7. X-RAY

8. CASE 1
12 YEAR OLD WITH OSTEOMYELITIS OF THE DISTAL RADIUS, WITH FOLLOWUP X-RAYS AT 1 MONTH, 6 MONTHS AND 4 YEARS DEMONSTRATING COMPLETE RESOLUTION. 

14. CASE 2
NEONATE CIRCUMCISED SINCE 25 DAYS. NOTE THE RIGHT UPPER MEDIAL TIBIAL METAPHYSEAL LYTIC LESION; THICK PERIOSTITIS AND INTERRUPTED SOFT TISSUES AROUND.

16. BRODIE ABCESS

17. Brodie abscess refers to an intraosseous abscess related to focus of subacute pyogenic osteomyelitis. 
Unfortunately, there is no reliable way radiographically to exclude a focus of osteomyelitis.
It has a protean radiographic appearance and can occur at any location and in a patient of any age.
It might or might not be expansile, have a sclerotic or nonsclerotic border, or have associated periostitis.

20. BONE TUBERCULOSIS

21. Bacilli reach his joints from some focus elsewhere.
When tuberculosis involves a patient's skeleton, it is the involvement of his joints that matters most his spine, hips, knees, feet, elbows, wrists, and shoulders, in this order of frequency, and occasionally his other joints also.
Bacilli reach his joints from some focus elsewhere.
So there are lesions in his lungs, and for signs of surgical tuberculosis in other parts of his body.
Look particularly for enlargement of his lymph nodes.
