How does the primary destruction pattern in typical vertebral osteomyelitis contrast with that of a Romanus lesion?
Answer
Destruction centered within the disc space symmetrically
Differentiating Romanus lesions from other causes of spinal damage, such as infection (osteomyelitis), relies heavily on the precise location and pattern of tissue involvement. In cases of discitis or typical vertebral osteomyelitis, the primary destructive process is centered more deeply within the intervertebral disc space itself, often affecting the adjacent vertebral endplates symmetrically. Conversely, the Romanus lesion is specifically marginal, focusing the erosive activity precisely at the interface where the annulus fibrosus attaches to the vertebral bone, rather than centrally within the disc structure.
