Insular arteriovenous malformations and hippocampal vascular tortuosity in a blast-exposed rat. Lateral views of the micro-CT angiogram 3D reconstruction demonstrating the intracortical arterial feeder vessels forming a large arteriovenous nidus. a, Lateral view of the brain vasculature. The box denotes an arteriovenous malformation in the insular cortex. Higher magnification images of this structure are seen in the insert white box in a, in b and c. d, Coronal optical section (approximate interaural coordinates 7.20–4.95 mm) showing increased arterial tortuosity in the frontal hippocampal region of one hemisphere. Scale bar, 1 mm in a, 0.1 mm in b, 50 mm in c, 1 mm in d
