CT angiography (CTA) axial slices (a1, a2, c1 and d1) also showed calcification at the same positions of the head CT scan: a1 and a2 to a (thick black arrow), c1 to c and d1 to d (thin black arrow), and the vessels are not enhanced. CTA with curved planar reformation (a ~ c) and with 3D reconstruction (d ~ g) showing that the left MCA is huge and tortuous and almost the same diameter from the beginning to the end (black arrow in a ~ c and white arrow in d ~ g). One small branch (yellow arrow) from the M1 segment and another small one (blue arrow) from the M2 segment
