29-year-old male presented with bilateral lower limb weakness. T2 sagittal dorso-lumbar spine (A) shows spinal cord expansion with high signal intensity. Pre-contrast T1 (B) and post-contrast T1 (C) show expansion of spinal cord with isointense signal and heterogeneous post-contrast enhancement. D and E rCBV was calculated in comparison to normal cord (yellow curve) and the curve shows hyper perfusion of the lesion (arrow to red curve). DWI at b value = 1000 (F) shows hyperintensity of the lesion (arrow) which looks also hyperintense at ADC map (arrow at G) denoting free diffusion. This lesion was diagnosed ependymoma (low grade)
