(a) Sagittal T2W1 showing cord expansion and hyperintense signal extending from the Th7 level to Th12 level surrounding both anterior and posterior aspects of cord. (b) Sagittal T1W1 showing an isointense mass with no clear-cut demarcation between cord and tumor. (c) Gadolinium contrast-enhanced MRI reveals slight enhancement. This is only a part of the tumor.

Sagittal images from T2-weighted imaging (T2WI) (Figure 1(a)) showed cord expansion and a hyperintense signal extending from the Th7 to Th12 vertebral level, surrounding both anterior and posterior aspects of the cord. Sagittal images from T1-weighted imaging (T1WI) (Figure 1(b)) revealed an isointense mass lesion with no clear-cut demarcation of the interface between the spinal cord and tumor. A small enhanced portion was seen with gadolinium administration (Figure 1(c)).
Axial T2WI at the Th8-11 level, showing an eccentric intramedullary tumor located bilaterally. Bars indicate levels of axial views for Th8 (a), Th9 (b), Th10 (c), and Th11 (d).

T2WI showed extension of the tumor along bilateral surfaces of the spinal cord with strong compression (Figure 2). The spinal cord was severely deformed from compression by the tumor.
