Primary Intradural Extramedullary Spinal Melanoma in the Lower Thoracic Spine

Figure 1

Preoperative sagittal MRI shows the spinal cord tumor at the level of the conus medullaris (arrow). T1-weighted MRI with gadolinium shows high signal intensity relative to that of the cord (a) and T2-weighted MRI shows inhomogenous hypointensive signal (b). Four weeks’ follow-up sagittal T1-weighted MRI with gadolinium (c) and T2-weighted MRI (d) and 28 weeks’ follow-up T1-weighted MRI with gadolinium (e) and T2-weighted MRI (f) show the residual tumor (arrow).
