Improvement of vessel tortuosity abnormalities during successful treatment. A: Axial slice of a T1-GAD baseline scan showing a large tumor (arrow). B: Lateral view of the vessels segmented from the baseline MRA. Rectangle outlines the region magnified in C. C: Tortuosity abnormalities involve both smaller branches and the large frontopolar arteries (arrows). D: The tumor has regressed at month 2 of treatment (arrow). E: At month 2 small, abnormal vessel branches have largely disappeared and there is normalization of the larger vessels’ shapes.
