Patient 15, a 66-year-old man with a history of bilateral lower extremity weakness. A, Sagittal T2-weighted MR image shows multiple serpiginous flow voids (arrow) within the sacrum and lower lumbar spine. B, Left anterior oblique right lateral sacral angiogram shows site of SDAVF (arrow). C, Frontal spot fluoroscopic image shows glue cast within the arterial feeder, site of the fistula, and outflow vein (arrow). D, Sagittal T2-weighted MR image 6 months after treatment shows some interval resolution of the multiple serpiginous flow voids (arrow) within the sacrum and lower lumbar spine.

Patient 1, a 59-year-old man with inability to stand and persistent retention. A, Sagittal T2-weighted MR image shows high signal within the conus medullaris, lower and midthoracic spinal cord (arrow). B, Right T12 angiogram shows filling of an SDAVF (small arrow) with initial filling of the epidural venous plexus (small arrow), which then fills the radicular veins (large arrow). C, Frontal spot fluoroscopic images showing Onyx cast. D, Sagittal T2-weighted MR image 3 months after treatment shows interval resolution of the high signal within the conus medullaris, lower and midthoracic spinal cord.
