case_images: A: Hyperacute left MCA (green arrow) with loss of gray-white differentiation at insular and subinsular region (yellow arrows) suggestive of developing ischemic infarct in the territory of the left MCA. B: Filling defect involving the left MCA from segment M1 onward (red arrow ). C: Thrombosis of the left ICA just proximal to the bifurcation extending to the communicating segment (red arrow).. MCA: middle cerebral artery, ICA: internal carotid artery

case_images: FIG2
case_images: A and B: Loss of gray-white matter differentiation with sulcal effacement over the left MCA territory (yellow arrows) suggestive of acute infarct with diffuse brain edema. It shows an interval increase in the extension of the hypo-attenuation to involve the left occipital, left temporal, and left parietal lobe (blue arrows). There is an interval development of 5 mm midline shift to the right side (green arrow). There is a mass effect noted on the left lateral ventricle (red arrow).. MCA: middle cerebral artery

case_images: Due to the progression of brain edema (Figure 3A and Figure 3B), the patient was given mannitol and then underwent an urgent decompression craniotomy and inferior vena cava (IVC) filter insertion to prevent proximal embolization from lower limbs.
