Female, 74 years old, with history of C3-C5 epidural abscess, evaluate for resolution on antibiotics. Previously demonstrated fluid within the left C4-5 facet joint, and edema in the facet complex and the surrounding paraspinal soft tissues, have nearly completely resolved. There does remain some ill-defined enhancement in these areas but this is also improved. Posterior epidural thickening at the L4 level has improved as well. No definite epidural or paraspinal fluid collections are seen.A dextroscoliosis of the cervical spine is redemonstrated. Grade 1 anterolisthesis of C4 relative to C5 is demonstrated. A grade 2 anterolisthesis of C5 relative to C6 is unchanged. Marked left facet degeneration is again seen at C3-4, C4-5 and C5-6. Mild spinal canal narrowing is redemonstrated at C4-5 and C5-6.
Interval improvement in signal abnormalities centered on the left C4-5 facet complex. No evidence of any residual epidural or paraspinal fluid collection is seen.
