(a) Sagittal T1-weighted MRI showing heterogeneous intradural subpial lesion from D5-D9 level. The anterior part is isointense (arrowhead) while posterior part is hyperintense (bold arrow); (b) Sagittal T2-weighted MRI showing the anterior part to be isointense with internal hypointensities (bold arrow) while posterior part remains hyperintense; (c) Sagittal postcontrast T1-weighted fat saturation images showing the signal suppression of the posterior part, while irregular enhancement can be noted in the anterior part (bold arrow)

T1 and T2 sequences while the anterior part was isointense on T1 and hypointense on T2-weighted sequences. The hyperintense signal of posterior part showed suppression on fat saturation images reflecting the presence of fat and the anterior part showed irregular enhancement on contrast administration [Figure 1a-c].
