Methicillin resistant staphylococcus aureus CT

• CT is more sensitive than plain films for the detection of early bone destruction and effusion in septic arthritis.
• On CT, features of bacterial osteomyelitis include overlying soft-tissue swelling, periosteal reaction, medullary low-attenuation areas or trabecular coarsening, and focal cortical erosions.
• In endocarditis a CT scan of the head should be obtained in patients who exhibit CNS symptoms or findings consistent with a mass effect (eg, macroabscess of the brain).
