Overview of the complications and sequelae in spinal infections.

Spondylitis or infection of the spine is a spectrum of diseases involving the bone, disks, and/or ligaments. Because of a significant increase in the immunocompromised patient population, spinal infections are a growing and changing group of conditions, making the diagnosis based on imaging more challenging. Most cases of spinal infections are pyogenic and occur after hematogeneous spread of an infection located elsewhere in the body. A prompt diagnosis remains crucial and MR imaging remains the cornerstone in the diagnosis. This article provides a pictorial overview of the complications and sequelae in spinal infections in general. Discussed are postoperative infections, extraspinal spread of infection, fractures and malformations, and neurologic complications.
