(a) Thoracolumbar spine magnetic resonance imaging (MRI) T2-weighted sagittal images in series showed an extradural T3 dumbbell-shaped tumor, that severely compressed the spinal cord non-homogenously hyperintense. (b) Thoracolumbar spine MRI T1-weighted sagittal images in series with Gadolinium in series showed an extradural T3 dumbbell-shaped tumor in-homogeneously enhanced with enlarged neuroforamina. (c) Thoracolumbar spine MRI T1-weighted axial image showed a left extradural T3 dumbbell-shaped tumor.

On MR, the lesion was hypointense on T1 studies, inhomogeneously hyperintense on T2 weighted images, and inhomogeneously enhanced with contrast (Type I according to Wang et al. classification) [Figure 1].

T3-T4 laminectomy for intracanalicular/ extracanalicular extradural tumor removal [Figure 2]. The frozen section diagnosis suggested a spinal chordoma, while the permanent specimen confirmed this diagnosis.
