A 93-year-old female with a paraspinal arteriovenous fistula (AVF) occurred within the lumbar spinal vertebral body was assessed with time resolved three-dimensional (3D) phase-contrast MRI (4D-Flow) on 1.5 Tesla MR scanner (GE Healthcare). The 3D vector field, streamlines, and pathlines analyses demonstrated uni-directional flow from the aorta to the large vascular cavity in the lumbar vertebral body by means of the lumbar artery as well as dilated paravertebral veins as drainers, which confirmed AVF, not aortic pseudoaneurysm. The 4D-Flow also showed an added value in planned endovascular surgery concerning localization of the precise shunting point and the shunting volume quantification. J. Magn. Reson.
