more florid than that
seen in hypertrophic

9. • Fig. 36.7 Chronic osteomyelitis.
(A) The preliminary radiograph
shows a deformed right femur.
There is cortical thickening with
evidence of intramedullary
cavitation and angulation. Linear
calcified densities in the soft
tissues may represent extruded
sequestra. (B) Coronal fat-
suppression MR image shows
muscle wasting; the deformity of
the bone is again demonstrated.
There is extensive increase in
signal within the medulla,
indicating a fluid collection. A
band of high signal can be seen
extending from the medulla
superiorly, through the cortex
laterally and into the adjacent soft
tissues. There is an effusion in the
knee joint and oedema of the
subcutaneous soft tissues. (C) The
sinogram shows contrast medium
in the same distribution as the
fluid in B.

medullary destruction and a smooth periosteal reaction. (B) The
radionuclide bone scan shows gross increase in uptake locally.
12. • Fig. 36.9 Chronic osteomyelitis: (C) On CT scanning, gross periosteal
reaction is demonstrated, causing considerable enlargement and sclerosis
of bone.(D) The MR scan shows the grossly altered signal in the affected
femoral neck and greater trochanter, with replacement of the normal
bright marrow signal on the T 1 – weighted image. Cortical changes are
demonstrated and a periostitis is seen.
13. Fig. 36.10 Early osteomyelitis. (A) There is a barely discernible radiolucency
affecting the distal shaft of the femur, but an early periostitis is
demonstrated medially and laterally. (B) The radioisotope bone scan
shows the extent of the pathological change.
14. • Fig. 36.11 Chronic osteomyelitis. The CT scan
shows the left side to be normal, while on the
right there is extreme cortical thickening and
marrow oedema of the tibia.

18. • Fig. 36,15 ' Tunnelling' in osteomyelitis. (A) A finger-like
process of osteomyelitic bone destruction extends from the
main focus. This is tunnelling, which usually indicates the
presence of chronic infection. (B) In another patient, the
sagittal fat-suppression MR sequence shows a vertically
orientated and fluid-filled cavity in the proximal tibia. It is
well defined and has all the features of a chronic infective
lesion. (C) The chronically thickened cortex together with
the central fluid-filled cavity lying within the medulla are
demonstrated on this axial fat-suppression MR image.
19. • Fig. 36.16 Brodie's abscess. The plain film was not
helpful. (A) The radioisotope bone scan confirms the
presence of a focal lesion in the upper cervical spine.
20. • Fig. 36.16 Brodie's abscess. (B) The CT scan shows
an appearance which could represent either an
osteoid osteoma or a Brodie's abscess, that is, an
area of osteolysis with central sclerosis and
surrounding it a well-demarcated zone of reactive
sclerosis. (C) Changes at MR mirror those seen at
CT in the lateral mass of C2.

adjacent to the fifth metatarsal head.

28. • Fig. 36.24 Chronic granulomatous disease. (A) There is a
localised metaphyseal defect surrounded by sclerosis.
These features are characteristic of chronic infection in a
child. (B) The MR scan confirms the presence of localized
metaphyseal abnormality with replacement of the local fat.
There is a mixture of destruction of bone, oedema and
reactive new bone formation at the margin of the lesion.

uptake in the proximal tibial metaphysic of the left knee.

epiphysis. Fluid replaces fat on both sequences. (Courtesy

37. Fig. 36.31 Tuberculous discitis. (A) The changes on the plain film are really quite
similar to those that would be seen with a simple infection. There is distal
destruction associated with irregularity of the overlying end-plates and some
reactive new bone formation. There is perhaps a suggestion on the plain film that
a soft-tissue mass is demonstrated anterior to the vertebral bodies. (B) The MR T,-
weighted axial image shows the end-plate defect seen so well on the plain film
but, in addition, psoas abscesses with central necrosis are demonstrated.
38. • Fig. 36.32 (A) The plain film shows features which are typical for spinal tuberculous disease. There is an
extensive paraspinal soft-tissue mass. Detail in the underlying spine is poor but there is early crowding of ribs
posteriorly, indicating early vertebral collapse. (B) Coronal MR image of the thoracic spine demonstrates
destruction of the intervertebral disc at the point where the paraspinal widening is maximal and this change is
associated with alteration of signal from the vertebrae. (C) The sagittal fat-suppression image shows increase in
signal in adjacent vertebral bodies together with anterior and posterior soft-tissue masses, the latter indenting
the spinal canal and compressing the adjacent cord.

articular surfaces on both sides of the hip joint, with narrowing of the joint
space and subarticular cyst formation. (B) At arthrography the presence of an
irregular and shrunken synovial capsule is demonstrated. Defects are shown in
the acetabulum and on the femoral head. Infection has resulted in a restrictive
capsulitis and destruction of cartilage and bone.

relatively early on in life as the metacarpals are shortened. The carpal
bones are fused following widespread osteoarticular destruction. The

calcification on the lateral view.
