The nodular calcifications were observed at the L3-4 interspinous space, the L2-3 and L3-4 ligamentum flavum, the bilateral L3-4 facet joints, and the location of left L4 spondylolysis (Figure 1).
An intensity change of the L1-4 supraspinal ligament in T1-weighted images, effusion at the L3-4 interspinous space in T2-weighted images, and a GD-enhanced epidural mass at the level of L4 vertebral body.

Sagittal magnetic resonance (MR) images (Figure 2) showed an intensity change of the L1-4 supraspinal ligament in T1-weighted images and effusion at the L3-4 interspinous space in T2-weighted images.

MR images showed an intra- or epidural lesion at L2-3 (Figure 3). Moreover, epidural GD-enhanced masses compressed the dural sac in the shape of a cross at the L3-4 (Figure 4) and L4-5 segments.
Epidural GD-enhanced masses compressed the dural sac in the shape of across at the L3-4.

(a) Aspiration of the L3-4 interspinous space yielded a murky, pus-like synovial effusion. (b) Multiple cultures of the synovial fluid tested negative for bacteria and fungi, whereas compensated polarized light microscopy revealed monocle or triclinic intracellular crystal with a positive birefringence.

A total of 1.2 ml of fluid with a murky, pus-like synovial effusion (Figure 5(a)) was aspirated from the L3-4 interspinous space under the fluoroscopic image. Polarized light microscopy revealed monocle or triclinic intracellular crystal with a positive birefringence (Figure 5(b)).
Flurbiprofen axetil was administered by intravenous drip injection for 3 days, and local and systemic inflammatory signs dramatically improved.
