case_images: Plain radiography showed expansion of the space between the arches at T12/L1 and L1/2.

case_images: Plain radiography showed that the T12 vertebral arch was partially lost and the space between the vertebral arches was expanded (Figure 1).
case_images: T2-weighted MRI showed a cystic lesion with T1-low/T2-high intensity at the T11-L1 level.

case_images: MRI showed a cystic lesion with T1-low/T2-high intensity at the T11 to L1 level (Figure 2).
case_images: CT after myelography showed scalloping of the vertebral arch at the T12 level, with contrast medium flowing into the arch. (a) A communication pathway was present between the dural canal and the cyst at the T12 level (b).

case_images: In addition, a communication pathway between the dural canal and cyst was present at the T12 level (Figure 3).
case_images: Intraoperative findings. (a) Partial loss of the bone cortex at the T12 vertebral arch. The communication pathway for cerebrospinal fluid in the axillary region of the left Th12 nerve root was ligated, and the cyst was excised.

case_images: Thus, this region was ligated and the cyst was excised. The cyst did not adhere to the dural canal (Figure 4).
