(a) Sagittal-contrasted enhanced T1-weighted magnetic resonance imaging showing strongly enhanced intradural extramedullary lesion at the T4-T5 level. (b) Axial view contrast-enhanced T1-weighted magnetic resonance image. (c) T2-weighted magnetic resonance image showing a hypointense mass with marked cord compression

The lesion is exerting a significant local mass effect, causing marked cord compression. The lesion was hypointense on T2-weighted image [Figure 1].
Computed tomography scan images. (a) Axial view of T4 vertebra showing a calcified lesion and osteosclerosis mainly of the right lamina and pedicle. (b) A lower cut of T4 vertebra showing increased hyperdensity. (c) Coronal view

On computed tomography scan, the lesion showed calcifications associated with osteosclerosis of the right lamina and pedicle [Figure 2].

With careful dissection under the microscope, we were able to remove the tumor in a piecemeal fashion [Figure 4].
Six-month follow-up magnetic resonance image of the spine showing complete removal of the tumor without signs of recurrence. (a) Sagittal view. (b) Axial view at the T4-T5 level
