Fig 3. MR images of patient 2 showing extensive EDC 1 day post-LP. A, Noncontrast T1-weighted image (TR/TE, 500/9) of the spine shows a low-signal-intensity EDC extending from the upper thoracic level of the spine to the sacral level. Elevated epidural fat pads (arrows) can be seen and appear heterogeneous due to fluid infiltration. B, Noncontrast T2-weighted image (TR/TE, 4000/126) of the spine shows high-signal-intensity EDC. Epidural fat pads (long arrows) are elevated, and the dura is deviated anteriorly (short arrows). C, Axial T2-weighted image (TR/TE, 4000/126) at the level of the conus shows heterogeneous signal intensity in the dorsal epidural space secondary to fluid elevating and infiltrating the epidural fat pads. There is resultant deviation of the dura anteriorly.
