Sagittal MRI images showing heterogeneous epidural posterior mass compressing thoracic cord over three body segments between T3-T5. (a) T1-weighted MRI shows inhomogeneous iso to hypointensity mass; (b) Post-contrast T1-weightted MRI shows enhancing mass; (c) T2-weighted MRI shows a hyperintense tumor

The magnetic resonance imaging (MRI) scan showed a large fusiform dorsal lesion measuring 8.0 cm x 2.8 cm x 1.1 cm compressing the thoracic spinal cord extending over the T3-T5 levels [Figure 1].

It was inhomogeneous, isointense on T1-weighted images, and hyperintense on T2-weighted images, showing intense enhancement after gadolinium administration and occupying the posterior aspect of the spinal canal [Figure 2].
