KEY FACTS


Imaging






image
Longitudinal US of a neonate with acute osteomyelitis of the femur shows focal cortical irregularity image at the distal femoral metaphysis. This is associated with periosteal soft tissue thickening image and a small amount of subperiosteal fluid image.


image
Lateral US of the contralateral femur of the same patient shows the smooth cortex of the femoral metaphysis image and normal thin hyperechoic periosteum image. The physis image and epiphysis image are normal.


image
Longitudinal US shows acute osteomyelitis with a focal bone erosion image filled by hypoechoic inflammatory soft tissue at the distal ulnar metaphysis with associated periosteal thickening image and a small amount of subperiosteal exudate image.


image
Longitudinal US shows partially mineralized, thickened mature periosteal reaction image deep to a large collection image due to chronic osteomyelitis in the femoral diaphysis. The femoral bony cortex image in this section is largely intact.
