Patient 19. Multiple VBDAs affecting bilateral vertebral arteries (VAs). A 49-year-old man complained of recurrent headache for more than 1 year. Catheter angiography of right VA showed intimal flaps (a, white and black arrow) in 2 lesions with angiographic finding of aneurysmal dilation. Left distal VA seemed to be absent on catheter angiography suggesting hypoplasia or acquired occlusion (a, white arrow head). TOF-MRA showed similar luminal finding as catheter angiography. For the proximal lesion of right VA, long- (c, arrow) and short-axis (d, arrow) reconstructed view of post-contrast VWI demonstrated intimal flap and double obviously. Similar findings were detected for the distal lesion of right VA (e, f, arrow). For the left VA, long- (g, arrow) and short-axis reconstructed view (H, arrow) of post-contrast VWI revealed obvious dilation of outer contour and chronic haemotoma corresponding to the distal portion of left VA, suggesting acquired occlusion duo to dissection
