Giant schwannoma of thoracic vertebra: A case report

Figure 1 Axial computed tomography revealed bone destruction visible in the T5 (A) and T6 (B) vertebrae and the right accessory and part of the right rib, and irregular soft tissue density shadows were seen in the T5 and T6 vertebrae, which protruded into the thoracic cavity to the right.

Figure 2 Sagittal and axial magnetic resonance imaging revealed tumor invasion at T5 (A1-4) and T6 (B1-4), and diffusion weighted imaging showed patchy high signals within the T5 (A5) and T6 (B5) lesions.

Figure 3 Sagittal and coronal magnetic resonance imaging revealed intravertebral occupancy at T6 (A1-2) and T5 (B1-2).
