Images of right basal ganglia BAVM in a 33-year-old woman, with several asynchronous draining veins toward sigmoid sinus and straight sinus. a 3D MIP of Silent MR angiography showed one deep draining vein with higher signal intensity (red arrow) and several small draining veins with lower signal intensity (arrowhead). b Lateral view of right ICA angiography. The deep draining vein (red arrow) was visualized at the same time as one frame after the nidus depiction on DSA. The small draining veins with lower signal intensity on Silent MRA (arrowhead) were observed four frames after the nidus depiction on DSA.
