Long segment T2 weighted sagittal images showing heterogenous intensity in the single lesion with hypointense caudal and hyperintense anterior and cranial areas. Serpentine flow voids can be seen caudal to the lesion in the epidural space. On T1 images mild hyperintensity of the lesion compared to the cord was present with the lesion extending in both subdural and epidural locations. Significant indentation on the dorsal cord and draping at its anterolateral recess present. On post-contrast images no enhancement of the lesion was present.
