POTT’S DISEASE:
Accurate interpretation of imaging requires experience and understanding of spinal anatomy and pathophysiology. The sources of spinal infection can be hematogenous spread through arterial vessels, postoperative infection, direct puncture or trauma and also spread from a contiguous focus Spinal spread is thought to be hematogenous in most instances. Anatomic distribution of vertebral vessels is age related. In adults, the richly vascularized vertebral zone is the vertebral body corner adjacent to end plate (spondylitis), and as such is the most common site of initial infection. Further the infection spreads within the vertebral body, to the opposite endplate, to the disk space (spondylodiskitis), to the vertebral arch, and beneath the anterior or posterior longitudinal ligaments, leading to extension of the infection to multiple adjacent or separate vertebral segments.
