The second MRI images of the thoracic spine. A) Sagittal T2-weighted MRI image shows a hyperintense lesion expanding the cord at the T6-7 spinal level. B) Sagittal T1-weighted MRI image shows an isointense lesion expanding the cord at the T6-7 spinal level. C) Coronal T1-weighted MRI image shows a ring-like enhancing intramedullary lesion (16 x 7 x 6 mm) with gadolinium.

MRI of the thoracic spine showed a hyperintense lesion expanding the cord from T6 through T7 on T2-weighted images, and on T1-weighted images there was an isointense lesion expanding the cord from T6 through T7 with ring enhancement after gadolinium diethylenetriaminepentaacetic acid (GDTA) administration (Figure 1A-C).
The MRI images of the thoracic spine at the time of neurologic deterioration. A) Sagittal T2-weighted MRI image shows an increase in the size of the lesion. B) Coronal T1-weighted MRI image shows an enlarged ring-like enhancing intramedullary lesion (40 x 10 x 7 mm) with gadolinium.
