Tuberculosis of the spine is common among osteoarticular tuberculosis and occurs in children and young adults. In children, the thoracic spine is more common, often involving several vertebrae, and in adults, the lumbar spine is more common, often invading two adjacent vertebrae. 90% of spinal tuberculosis lesion signs are in the vertebral body, and simple adnexal tuberculosis is rare. The imaging manifestations are as follows: 1) bony destruction of the vertebral body or adnexa with round or irregular-shaped bony defects, or vesicular depressed destruction of the anterior edge of the vertebral body, narrowing or loss of the vertebral space; 2) destruction and herniation of the intervertebral disc and cartilage endplates into the vertebral body, and later fusion of adjacent damaged vertebral bodies, which is an important basis for the diagnosis of spinal tuberculosis; 3) posterior protrusion deformity, which is one of the more characteristic manifestations of spinal tuberculosis and can be accompanied by bending, mostly seen in adolescents and children with thoracic spinal tuberculosis, due to extensive lesions and obvious destruction of multiple vertebral bodies; 4. cold abscesses, caseous abscesses in the soft tissues surrounding the diseased vertebrae, and lumbar spinal tuberculosis can form a lumbaris major abscess, which is manifested by the lumbaris major muscle protruding outward in an arc. Thoracic spine tuberculosis forms paravertebral abscesses, which manifest as swelling of the soft tissues of both sides of the thoracic vertebrae in the shape of a spindle. Thoracic spine tuberculosis forms a widening of the soft tissue of the posterior pharyngeal wall and protrudes forward in an arc, and irregular calcification is seen in cold abscesses of longer duration; 5. Dead bone, which often manifests as sandy dead bone.
