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.
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.
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.

21. 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.
