Safety and efficacy of posterior approach for resection of spinal meningioma: Impact of dural attachment location

Figure 1 Imaging finding in case 1. A: Sagittal; B: Coronal; C: Axial 3-dimensional CT images revealed calcification within the tumor; D: Subsequent sagittal; E: Coronal; F: Axial magnetic resonance imaging T1-weighted post-contrast-enhanced images demonstrated homogeneous contrast enhancement of the tumor, which was located in the thoracic spine with ventrolateral dural attachment; G: Sagittal magnetic resonance imaging (MRI) T2-weighted image displayed gross-total resection of the tumor; H: Sagittal MRI T2-weighted image displayed no recurrence of the tumor observed 3 years after surgery; I: Lateral; J: Anteroposterior X-ray images depicted pedicle screw fixation and posterolateral bone graft fusion procedures that were conducted to stabilize the spine.
