Dorsalgia, unspecified [M54.9], Reason for Study: ^Reason: 45 yof with S epi bacteremia, previous hardware in lumbar spine, spinal tenderness throughout, evaluate for epidural abscess History: Bactermia Postoperative status of the lower lumbar spine, screws and plate with external fixation from L4 to S1.There is normal cervical lordosis. The cranial-cervical junction is normal. There is normal thoracic kyphosis and lumbar lordosis. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The cord signal is normal. The conus medullaris terminates at the level of L1.Bilateral pleural and adjacent lung tissue enhancements are seen indicating pleural effusions with possible subsegmental atelectasis. If clinically indicated, dedicated lung CT scan can be considered.There are enhancements around the instrumentations and adjacent soft tissues indicating postoperative changes. However there is no evidence of postoperative unusual enhancements on lumbar spine.There is mild diffuse bulging of disc at the level of C56 which abuts thecal sac. Otherwise cervical spine intervertebral discs appear to be normal.Thoracic vertebral intervertebral discs are within normal limits.There is diffuse bulging of disc and disc height reduction at the level of L34. Associated with bilateral ligamentum flavum thickening, there is moderate to severe spinal canal stenosis at this level.Disc dessication is seen at the level of L5S1 with minimal anterolisthesis of L5 on S1. There is spinal canal widening from L4 to S1 level which is postoperative changes.
1. Postoperative no unusual finding.2. Diffuse disc bulging at the level of C56.3. Moderate to severe spinal canal stenosis at the level of L34 as described above.4. No abnormal enhancement except bilateral pleural enhancement as described above.
