vertebral osteomyelitis

Figure 1a: 65-year-old man with vertebral osteomyelitis due to Mycobacterium avium-intracellulare. Sagittal T1-weighted image shows hypointense lesion from L4 to L5, extending to the prevertabral region (arrows).

Figure 1b: 65-year-old man with vertebral osteomyelitis due to Mycobacterium avium-intracellulare. Sagittal T2-weighted image obtained at the same level as A shows very hyperintense areas in the extended region and in the L4-5 intervertebral disc. (arrows).

Figure 1c: 65-year-old man with vertebral osteomyelitis due to Mycobacterium avium-intracellulare. Sagittal T1-weighted image obtained after gadolinium injection at the same level as A shows Rim-like enhancement in the lesion (arrows).

Figure 1d: 65-year-old man with vertebral osteomyelitis due to Mycobacterium avium-intracellulare. Axial T1-weighted image obtained after gadolinium injection at the level of L4-5 shows Rim-like enhancement (arrows).

-Osteomyelitis most often occurs as a result of trauma producing open wounds that allows the entry of bacteria into the body, as a result of surgical procedures, or as a result of bacteria circulating in the bloodstream—a condition known as bacteremia. Osteomyelitis of joints can affect their function by means of bone destruction and joint deformity.
