Figure 2 Pre-operative evaluations. A-B: T2-weighted magnetic resonance imaging in axial view (A) and fast spin echo, fat-suppression coronal view (B) showing a cystic pouch laterally surrounding the spinal nerve root at left T3 level (arrow), which may be derived from the neural foramen of the L3 level. The air-fluid level was also demonstrated (arrow); C) Axial view of chest computed tomography showing pneumothorax and subcutaneous emphysema (arrow); D) Poorly healing previous thoracoscopic access wound.
