Sagittal postcontrast MR images of patient 19 showing very extensive EDC 1 day post-LP. A, Contrast-enhanced T1-weighted image (TR/TE, 500/14) shows high-signal-intensity EDC, which extended from C7-L4 (cervical images not included). B, Contrast-enhanced T2-weighted image (TR/TE, 4000/115) shows very-high-signal-intensity EDC, hyperintense to CSF, with compression of the thecal sac and anterior deviation of the dura (short arrows). Heterogeneous floating fat pads (long arrows) are more obvious on the T2-weighted image.
