Figure 6. Osteomyelitis in a 25-year-old diabetic man with burning foot pain. Sagittal gadolinium-enhanced fat-suppressed T1-weighted MR image demonstrates a low-signal-intensity fluid collection with peripheral enhancement representing an abscess plantar to the fifth metatarsal head (arrows). Note also the intense enhancement of the adjacent fifth metatarsal bone (*), a finding that indicates osteomyelitis.
