case_images: (a) Axial T1-weighted MRI, (b) sagittal T1-weighted MRI, and (c) sagittal T2-weighted and short tau inverted recover MRI images demonstrating a large left T2-T3 synovial facet cyst within the spinal canal.

case_images: T2-T3 on the left side. There was no contrast enhancement. There was severe cord compression. There was acute cord signal change at the T2 level (Figure 1).
case_images: Microscopic image showing denuded cyst lining with focal synovium present. Gross specimen size 4.0 x 1.3 x 0.5 cm.

case_images: T1, T2, and T3 was performed followed by complete excision of a large 3 cm x 1.5 cm synovial cyst (Figure 2). The cyst was noticed to be originating from the left T2-T3 facet and demonstrated adhesions to the dura but was clearly extradural.
case_images: Sagittal, precontrast (a) and postcontrast (b), and axial postcontrast (c) MRI sequences 3 months postoperatively demonstrating maintained surgical decompression and no recurrent cyst formation.

case_images: A follow-up MRI was obtained three months postoperatively and revealed persistently adequate decompression of the spinal cord with no cyst recurrence as compared to preoperatively (Figure 3).
