Answer

Radiographic changes associated with Pott disease present relatively late. The following are radiographic changes characteristic of spinal tuberculosis on plain radiography: [35]

  • Lytic destruction of anterior portion of vertebral body

  • Increased anterior wedging

  • Collapse of vertebral body

  • Reactive sclerosis on a progressive lytic process

  • Enlarged psoas shadow with or without calcification

Additional radiographic findings may include the following:

  • Vertebral end plates are osteoporotic.

  • Intervertebral disks may be shrunk or destroyed.

  • Vertebral bodies show variable degrees of destruction.

  • Fusiform paravertebral shadows suggest abscess formation.

  • Bone lesions may occur at more than 1 level.
