Article Figures & Data

Figures

  • FIGURE 1.
    FIGURE 1.

    Plain film (A) and axial CT scan of L3 (B) showing inferior endplate erosion and evidence of periostitis (arrows).

  • FIGURE 2.
    FIGURE 2.

    99mTc-MDP bone scan (A) in anterior and posterior projections showing mild activity at L3. More intense uptake is incidentally seen at compression deformity surrounding T11. 67Ga-citrate scan (B) at 24 and 48 h in posterior projection shows progressively increasing uptake in mid lumbar spine.

  • FIGURE 3.
    FIGURE 3.

    (A) SPECT/CT of 99mTc-MDP bone scan showing that activity is localized to fixation screws and does not involve disk space or bone fragments. (B) SPECT/CT of 67Ga scan showing that spatially discordant uptake involves disk space and inferior endplate of L3 and extends anteriorly to allograft.
