A, T2 sagittal MR imaging of the thoracolumbar spine with fat saturation shows a longitudinal posterior epidural fluid collection (arrows). B, T2 axial MR imaging through the T8 vertebra shows the posterior epidural fluid collection (arrow) extending around the sides of the thecal sac.

A, Spot anteroposterior (AP) radiograph of the lower cervical spine shows placement of the first C5-C6 sublaminar posterior epidural needle. B, Spot AP radiograph of the cervicodorsal spine shows placement of the second and third posterior epidural needles at the T1–T2 and T4–T5 levels.

A, Midline noncontrast T1 sagittal brain MR imaging before emergent fibrin epidural patch demonstrates severe crowding of the posterior fossa with effacement of the basal cisterns and tonsillar descent through the foramen magnum (broken line). Note acute angulation of the distal basilar artery (arrow) and compression of the vein of Galen by the splenium of the corpus callosum (arrowhead). B, Repeat MR imaging with the same parameters performed 2 weeks after treatment and recovery. There is a normal appearance of the posterior fossa cisterns and gentle curvature of the basilar artery with resolution of distal kinking (arrow). Encephalomalacia in the splenium (arrowhead) from ischemia, which likely occurred because of compression of the splenial artery or draining veins.
