case_images: Sagittal T2-weighted Dixon fat saturated (a) and T1-weighted FLAIR (b) images showing blood collection within the thecal sac extending from the level of the L4-L5 decubitus base down to the level of S1-S2. This is most pronounced at the level of L5-S1 where the hematoma occupies the entire thecal sac and surrounds the cauda equina (arrow).
