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.
