Early ischemic changes and posterior linear hyperintensity. MRI findings of a 73-year-old woman who noticed muscle weakness and paresthesia in the lower limbs were obtained 11 h from symptom onset (a–c). On T2-weighted images, the lesion was marginally high but not definitive (arrow, a); however, it was evident on DWI and ADC maps (arrows, b and c) and indicated spinal cord infarction. A 77-year-old man suddenly experienced back pain and gait difficulty and underwent MRI 4 days after symptom onset. Slight T2 hyperintensity was observed at the C7–T1 level of the cord (arrow, d), which was clearly high on DWI (arrow, e; posterior linear hyperintensity) and low on ADC maps (arrow, f). The lesion suggested ischemia of the posterior spinal artery. ADC, apparent diffusion coefficient; DWI, diffusion-weighted imaging; MRI, magnetic resonance imaging
