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.
