Fig 3. Sacral SDAVF in a 64-year-old male patient visualized by MRA and DSA. Advantage of MRA in demonstrating vascular abnormality in a large FOV.
A, Sagittal T2-weighted image showing extensive spinal cord edema and only some enlarged vessels raising the suspicion of a vascular spinal cord abnormality (small white arrows).
B, Sagittal MIP of the MRA examination showing the overview and localization of an early filled and dilated vein (small black arrows).
C, In the enlarged view, the dilated vein of the filum terminale is more clearly depicted (black arrows).
The coronal target MRA MIP shows the arterialized filum vein (D, small black arrows) in the same projection in which DSA (E) could confirm the localization of the very small shunt at the first sacral level (gray arrow).
