Contrast-enhanced follow-up MRI performed 4 weeks after symptom onset. a Sagittal T2-weighted image showing vertical linear foci of high T2-weighted signal located anteriorly within the lower spinal cord (arrow). b Sagittal T1-weighted image after contrast injection demonstrating newly occurred intramedullary contrast enhancement (arrow) and persisting enhancement of the conus medullaris and descending nerve roots. c Axial T2-weighted image revealing bilateral circular foci of high T2-weighted signal in the anterior portion of the spinal cord at L1 level (arrows), also referred to as owl-eyes sign, suggestive of a mature infarction. d Sagittal T1-weighted image without contrast mean (left), sagittal T2-weighted fat-suppressed image (middle) and sagittal T1-weighted subtraction image after gadolinium-based contrast mean injection subtracted by the native T1-weighted image showing focal oedema in the posterior portion of the Th9 and Th10 vertebral bodies with associated contrast uptake, suggestive of vertebral body infarction
