Preoperatively, MRI of thoracic vertebrae showed strip-like equal T1 signals in the spinal canal at the level of T1-T3 vertebrae, low and equal T2 signals, and high signals in fat-suppression sequence. The contrast-enhanced T1 weighted phase showed obvious uniform enhancement. The meningioma located on the left posterolateral side of the spinal cord, and growth outward at the level of T2-3 intervertebral foramen. (A) Sagittal T1-weighted, (B) Sagittal T2-weighted, (C) Sagittal T2-weighted fat-suppression sequence, (D) axial T2-weighted, Sagittal (E) and axial (F) of the contrast-enhanced T1 weighted phase.

T1-T3 vertebrae, low and equal T2 signals, and high signals in the fat-suppression sequence. The contrast-enhanced T1 weighted phase showed a uniform enhancement, with clear borders and wide base attachments close to the dural membrane. The meningioma was located on the left posterolateral side of the spinal cord, and dumbbell-type growth was outward at the level of the T2-T3 intervertebral foramen (Figure 1).
Photomicrographs of the surgical specimens showing sheets of meningothelial cells with oval nuclei characteristic of meningioma (H&E, x200).

The CT-mediated biopsy of the T2-T3 intervertebral foramina lesion showed meningioma (Figure 2).
