Figures
- fig 1.
A 48-year-old man with occipital headaches, neck pain, and Wallenberg's syndrome.
A, Selective angiogram of the left VA shows typical aspect of stenotic dissection with a long stenosis (arrows) involving the V3 and V4 segments of the VA.
B, Early follow-up conventional angiogram, obtained at 4 months, shows a normal left VA (arrow) with complete resolution of luminal abnormalities.
C, Contrast-enhanced MR angiogram, obtained 29 months later, shows normal appearance of the left VA (arrow).
- fig 2.
A 37-year-old man with neck pains and vertigo after minor cervical trauma.
A, T1-weighted axial MR image (obtained 1 day after B) at the C3−C4 level, shows a typical aspect of dissection of the right VA, including a crescentic high signal (arrow) of the mural hematoma surrounding a narrowed signal void (arrowhead) of the residual lumen.
B, Arch aortogram with oblique view. The left VA appears normal (arrow), whereas the right VA is not visible, suggesting its complete occlusion. A selective angiogram of the right subclavian artery confirmed the diagnosis of VA occlusion.
C, Oblique view selective angiogram of the right VA, obtained at 3 months, shows recanalization of the artery (arrow) without residual luminal irregularities.
D, Contrast-enhanced MR angiogram, obtained at 8 months, with selective subvolume MIP reconstruction of VAs, shows a normal appearance of the right VA (arrow), consistent with findings revealed by conventional angiography.
- fig 3.
A 45 year-old-woman with severe headaches.
A, Oblique-view selective conventional angiogram of the left VA shows aneurysmal-type dissection, with a 3-mm-diameter pseudoaneurysm (arrow) involving the V3 segment of the artery.
B, Oblique view MR angiogram shows good analysis of the entire length of the left VA (arrows), with resolution of the pseudoaneurysm.
- fig 4.
A 39-year-old man with neck pain and Wallenberg's syndrome.
A, Arch aortogram shows a small left VA (arrow), whereas the right VA is not visible.
B, Contrast-enhanced MR angiogram, obtained at 2 months, shows complete recanalization of the right VA, with a fusiform pseudoaneurysm in its intradural segment (arrow).
C, Contrast-enhanced MR angiogram, obtained at 6 months, shows a normal aspect of the right VA (arrow), with a complete resolution of the pseudoaneurysm.
D, T1-weighted MR image, obtained at 9 days, shows a typical aspect of dissection of the intradural segment of the right VA with a crescentic high signal (arrow) surrounding a narrowed signal void (arrowhead).
E, T1-weighted axial MR image, obtained at 6 months, shows a spontaneous resolution of the mural hematoma of the right VA (arrow).
