Figure 10 Osteomyelitis with intraosseous and soft tissue abscess secondary to methicillin-resistant Staphylococcus aureus infection. A: Axial T2-weighted fat suppressed image shows intraosseous abscess cavity (solid arrow) with rim of surrounding edema and large surrounding soft tissue fluid collection (dashed arrow). Note T2 hypointense rim (arrowhead) forming the “double-line” sign; B: Axial T1-weighted post-contrast image shows peripheral enhancement associated with the intraosseous abscess (solid arrow) and soft tissue abscesses (dashed arrows).
