Fig 4. Sagittal MR images of patient 5 showing initial EDC 4 days post-LP and resolution of EDC 13 days later. A, Noncontrast sagittal T1-weighted image (TR/TE, 500/12) shows hypointense EDC extending from T12-S2. Epidural fat pads (arrows) are shown to be elevated and infiltrated with low-intensity fluid. B, Noncontrast sagittal T2-weighted image (TR/TE, 5000/135) obtained at the same time as A shows hyperintense fluid deviating the dura anteriorly (short arrows) effacing the CSF and elevating the fat pads (long arrows), which are infiltrated with fluid. C and D, Sagittal T1-weighted (C) (TR/TE, 500/12) and sagittal T2-weighted (D) (TR/TE, 5000/133) images obtained 17 days post-LP show resolution of EDC. Epidural fat pads (arrows) are normal in position and homogeneous. The dura is no longer deviated, and the intrathecal CSF is not effaced.
