Figure 1.
Preoperative MRIs. The right parasagittal T2-weighted (A), the axial T1-weighted (B), and the axial T2-weighted (C) MRIs show a well-defined, crescent-shaped, cystic mass lesion in the epidural space, located right posterolaterally in the canal, adjacent to the right T2-T3 facet joint (i.e., juxtafacet cyst [JFC], arrows). Note the joint effusion in the right T2-T3 facet joint space shown by the axial MRIs (arrow heads).

Figure 2.
Preoperative CT scans. The midsagittal reformatted CT image (A) shows a reduced cervical lordosis and mild spondylolisthesis of T2 on T3 (arrow). The axial CT images (B) indicate the severely degenerated facet joints bilaterally at C7-T1 through T2-T3 with spontaneous facet fusion at C7-T1 and T1-T2.

Figure 3.
Intraoperative microscopic views. Operative photographs following laminectomy with medial facetectomies at T2-T3 level on both sides and the removal of the ligamentum flavum, showing the JFC adjacent to the right T2-T3 facet joint (arrows) under a low (A) and a high magnification (B) of the microscope. Firm adhesion between the cyst wall and the dura (C) was dissected off with mostly a blunt microdissection resulting in a complete cyst removal (D).

Postoperative MRIs at 2 months. Midsagittal T2-weighted (A), axial T1-weighted (B), and axial T2-weighted (C) MRIs, showing complete cyst removal with adequate decompression of the spinal cord.
