71-year-old male presented with bilateral lower limb weakness and tingling sensation. T2 sagittal cervico-dorsal spine (A) shows interrupted areas of high signal intensity involving the cord opposite lower cervical and upper dorsal vertebrae. Pre-contrast T1 (B) and post-contrast T1 (C) show homogenous 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 lesions (arrow) which appears also at ADC map (G) denoting free diffusion. This lesion was diagnosed as Para neoplastic myelitis
