Figure 1 :CCT brain of patient with right MCA infarct. EIC evident at 4 h after onset are sulcal effacement (green arrow), parenchymal hypoattenuation (purple arrow). (C-caudate, L-lentiform, IC-internal capsule, l-insular ribbon, Ml-anterior MCA cortex, M2-MCA cortex lateral to insular ribbon, M3- posterior MCA cortex, M4, M5, and M6 are anterior, lateral, and posterior MCA territories immediately superior to Ml, M2, and M3, rostral to basal ganglia, A-anterior and P- posterior circulation). At 24 h, parenchymal hypodensity (yellow arrow) and petechial hemorrhagic transformation (red arrow)
