23-year-old male presented with headache. T2 sagittal cervical spine (A) shows long segment of CSF signal intensity involving cervical and upper dorsal cord. Pre-contrast T1 (B) and post-contrast T1 (C) show CSF signal intensity of the lesion with no post-contrast enhancement. D and E rCBV was calculated in comparison to normal cord (yellow curve) and the curve shows hypo perfusion of the lesion (arrow to red curve). DWI at b value = 1000 (F) shows no areas of high signal intensity within cord at site of lesion which appears also at ADC map (G) denoting free diffusion. This lesion was diagnosed as syrinx associated with Chiari I malformation
