A 20-year-old male patient with weakness and wasting of the left hand muscles. Neutral position sagittal T2-weighted image (A) shows the normal appearance of the cervical cord. Axial T2-weighted flexion MR images (B and C) and postgadolinium T1 fat-suppressed images (D and E) show widening of the LDS with anterior displacement of the posterior dura and asymmetric cord atrophy, more on the left side, along with multiple flow voids within the posterior epidural space (arrow). Postgadolinium T1 fat-suppressed flexion MR sagittal image (F) shows an enhancing posterior epidural venous plexus extending from the C4 to T4 vertebral level (block arrow).
