Overview

MRI is useful to confirm the extent of disease spread and involvement of the surrounding soft tissue. Complete spine MRI must be obtained to rule out non-contiguous lesions. MRI is the diagnostic investigation of choice for the diagnosis of spinal tuberculosis.

MRI

Findings on MRI to determine the extent of the disease include the following:

• Presence of abscesses and involvement of the vertebral body which appears as a change in the bone marrow signal intensity.
• Disc destruction
• Cold abscess
• Vertebral collapse
• Presence of intramedullary or extramedullary tuberculoma, spinal cord cavitation
• Spinal canal narrowing
