View larger version (87K): [in this window] [in a new window]   Fig 1. Axial gray-scale sonogram of the right CCA demonstrates concentric wall thickening (arrows) and a soft crescentic plaque (arrowhead).

View larger version (85K): [in this window] [in a new window]   Fig 2. Axial CTA images of the right ICA at presentation (A and C) and at 5 months (B and D). A, An eccentric fatty plaque (arrowhead) is seen in the ICA (–5 HU). B, Resolution of the fatty plaque is noted. C, Concentric wall thickening (arrowheads), narrowing of the lumen, and effacement and stranding of the fat in the carotid space are seen at a level superior to A. D, Resolution of the mural thickening and increased caliber of the ICA, with return of some fatty attenuation in the carotid space, are noted.

View larger version (80K): [in this window] [in a new window]   Fig 3. Right ICA at presentation (A) and at 5 months (B). A, Axial fat-suppressed postcontrast T1-weighted image demonstrates enhancement of the ICA wall and a fatty plaque (arrowhead) deep to the intima. Arrow indicates right external carotid artery (ECA). B, Axial fat-suppressed T1-weighted image demonstrates resolution of mural thickening and high signal intensity; disappearance of the fatty plaque with irregular mural thickening is now seen (arrowhead), consistent with scarring or residual inflammatory tissue. Arrow indicates right ECA.
