Abstract:
OBJECTIVETo investigate the value of MRI follow-up in pediatric patients with spinal tuberculosis.
METHODSFrom February 2004 to April 2013, MRI imaging data in 21 children with spinal tuberculosis by pathologically and clinically proven were retrospectively analysed. There were 11 males and 10 males, with an average age of 9.4 years old ranging from 2 to 14 years old. Eighteen patients were received conservative treatment, 3 patients were treated by surgical operation. The course of disease ranged from 2 months to 3 years. All cases underwent two or more MRI examinations for follow-up. MRI findings of the first and second examination were comparatively analyzed,including signal changes of vertebral body and intervertebral, paraspinal abscess and the change of kyphosis angle.
RESULTSIn the 21 cases with tuberculosis, 85 vertebral bodies were affected in total, including 10.6%(9/85), 49.4%(42/85) and 40%(34/85) vertebral bodies separately in the cervical,thoracic, lumbosacral spine. Follow-up MRI showed vertebral body shape and signal had no obvious change during or after treatment, 15 cases with vertebral bodies changed flat or cuneate, 10 cases with disc involvement,and intervertebral space became narrowing at different level. Among 13 patients with kyphosis angle greater than 0°, 7 were located on thoracic, 2, 3, 1 were on thoracolumbar, lumbar and cervical spine, respectively. Among 18 cases with conservative treatment,kyphosis angle were 0° on the first and the follow up MRI of 8 patients. One case of mild (<10°) kyphosis,follow-up MRI during therapy showed the angle slightly increased; 5 cases with moderate (10° to 30°), follow-up MRI during therapy showed no obvious change; 4 cases with severe (>30°), follow-up MRI during and after therapy showed kyphosis increased in varying degrees.
CONCLUSIONFollow-up MRI can make a big difference in the spinal tuberculosis of children; it can clearly show the change of the vertebral body and intervertebral space, paraspinal abscess and the kyphosis angle after the treatment,which can provide reference for clinical treatment and estimating prognosis.
