Brain MRI of lesions associated with SCD. (A) Maximal intensity projection reconstruction of a 3D-TOF MRA, showing occlusion of the distal segment of internal carotid arteries (arrowheads). (B-D) Axial 2-dimensional fluid attenuated inversion recovery (2D FLAIR), showing a territorial infarct (B, arrowheads), an isolated lacune (C, arrowhead), and white matter hyperintensities of presumed vascular origin (D, arrowheads).
