Fig. 1A. 46-year-old man with left-sided Horner's syndrome and headaches.
Carotid arteriogram shows aneurysmal type of dissection (arrow) with
small aneurysm located in subpetrous segment of left internal carotid artery
(ICA). Note kink redundancy and luminal stenosis (arrowhead).

Fig. 1B. 46-year-old man with left-sided Horner's syndrome and headaches.
Coronal MR angiogram obtained 3 months after A shows unchanged
aneurysm. Note good correlation with conventional angiography (arrow)
and resolution of luminal stenosis.

Fig. 2A. 45-year-old man with right-sided painful Horner's syndrome. Carotid
arteriogram shows aneurysmal type of dissection (arrow) with saccular
aneurysm located in mid cervical segment of right internal carotid artery
(ICA). Note luminal stenosis (arrowhead).

Fig. 2D. 45-year-old man with right-sided painful Horner's syndrome.
Follow-up axial MR angiogram centered on dissected ICA shows residual aneurysm
(arrow) because of higher resolution. This aneurysm decreased in size
more than 50%.
