Definition / general
  • Infection of bone (osteitis) or bone marrow space (myelitis) = osteomyelitis
  • Usually pyogenic, fungal or tubercular
  • HIV+ patients may be infected by unusual organisms (eg. Mycobacterium avium)
  • Radiographically may resemble a neoplasm, particularly after antibiotic treatment
  • Severe osteomyelitis is not associated with grade IV sacral decubitus ulcers in non-septic patients; imaging may be misleading (Arch Pathol Lab Med 2003;127:1599)
  • May cause secondary AA amyloidosis
Radiology description
  • Permeative, destructive lesion with periosteal new bone formation
  • Chronic osteomyelitis may produce focal destruction or focal abscess
