Ocular Infection Preceding Major Epidural Abscess

Figure 1

(a) T2 weighted image. A 2-3 mm anterolisthesis of L4 with respect to L5 is demonstrated; vertebral bodies are otherwise normally aligned. Increased signal intensity and a wall enhancing fluid collection are seen in the posterior epidural space. This extends from L2 to S1; the arrow depicts the upper extent. (b) T2 weighted image. Loss of vertebral body height and increased endplate concavity at T9, L3, and L4. Accompanying linear areas of signal loss are characteristic of fractures parallel to the superior end plates of T9 and L4. An anterior epidural abscess component is shown from L3 to L4. Posterior extension of the abscess is shown to S1 level as indicated by the arrow.
