 Again seen at T10-T11 is disc height loss, endplate erosive changes, and T2 hyperintensity involving the disc space and the adjacent T10 and T11 vertebral bodies. There is associated abnormal enhancement of the vertebral bodies and the T10-T11 disc. There is mild loss of height involving the T10 and T11 vertebral bodies similar to prior. Edema and enhancement extends into the posterior elements. Compared to prior, there is improvement in the T2 hyperintensity within the disc space and progressive loss of disc height. Mild focal kyphosis is noted at this level, similar to prior.There is disc bulge at the T10-T11 level which results in effacement of the ventral thecal sac and deformity of the thoracic cord at this level. There is enhancement involving the epidural space including the bilateral neural foramina as well as the paraspinous soft tissues at the T10-T11. Epidural tissue appears decreased in comparison with the noncontrast sequences; please note prior imaging was without contrast. No discrete epidural abscess however is appreciated on the current study. No discrete abscess involving the paraspinous soft tissues is appreciated. There is narrowing of the T10-T11 neural foramina bilaterally.Remainder of thoracic vertebral bodies are appropriate height and alignment. No significant spinal canal or neural foraminal stenosis is seen in the remainder of the thoracic spine. There are small bilateral pleural effusions.
Please note prior imaging was obtained without gadolinium. Compared to 4/21/2015, there is interval improvement in T2 hyperintensity within the T10-T11 disc space and progression of disc height loss. Enhancement involving the T10 and T11 vertebral bodies and the T10-T11 disc space persists but may be compatible with treated infection. No findings to suggest worsening infection. No epidural abscess is seen on the current study.There is persistent moderate spinal canal stenosis at the T10-T11 level with mild deformity of the thoracic cord. No new cord signal abnormality. Mild loss of vertebral body heights at the T10 and T11 levels and focal kyphosis at these levels again noted.
