MRI image of the thoracic spine (sagittal plane) showing an epidural mass (red arrows) with a clear border measuring 11 x 16 x 11 mm located at the level of 2 thoracic vertebrae (T7-T8). The mass was iso-intense on T1-weighted images (A) and showed mixed-signal intensity on T2-weighted images (B).

T1-weighted images (T1WI) and mixed-signal intensity on the T2-weighted images (T2WI). The T1-weighted transverse plane showed that the lesion occupied more than half of the T7-8 canal (Figure 1). It also showed that CD31 was positively expressed in the epithelial cells of the cyst walls (Supplementary Figure 1).
