Preoperative MRI (a) T2-weighted MRI sagittal scan with extensive intramedullary high intensity from C5 to C7. (b) T1-weighted MRI sagittal scan with contrast enhancement at level C5 -C6. Contrast enhancement is at the point of greatest spinal cord compression

T2-weighted sagittal images extending from C5 to C7 [Figure 1a], whereas the axial images confirmed the intramedullary signal abnormality. The T1-weighted MRI sagittal scan showed the lesion enhanced with contrast at the C5-C6 level [Figure 1b].
Postoperative MRI. (a) One month after surgery, sagittal MRI demonstrated slight decrease of the intramedullary high intensity on T2-weighted images. The high-intensity signal is still atypically extended beyond the point of compression. (b) T1-weighted MRI sagittal scan with persisting contrast enhancement at level C5-C6 1 month after surgery

The cervical MRI performed 1 month later demonstrated no significant changes in the intramedullary lesion [Figure 2].
