Figure 2. MR work-up. (a) Mid-sagittal T2 weighted image showing spinal cord compression at the T9–T10 level, with abnormal hyperintensity within cord parenchyma. (b) Mid-sagittal T1 weighted image showing hypointensity on the margins of the "pseudoarthrosis" due to reactive hyperostosis (arrowheads), and fatty bone marrow within central areas of the protruded ossicles (arrows). Normal epidural fat is present up and below the level of the intracanalar abnormalities (double ball-arrowheads). Compare similar slice location on CT image (Figure 1a).
