54-year-old female presented with incidental cervico-medullary junction lesion. T2 sagittal cervical spine (A) shows small hyperintense lesion at cervico-medullary junction with peripheral hypointense rim. Pre-contrast T1 (B) and post-contrast T1 (C) show isointense lesion with no significant 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 at site of lesion (arrow) which appears also at ADC map (G) denoting free diffusion. This lesion was diagnosed as cavernoma
