case_images: MRI brain (A,B): FLAIR showed multiple focal T2W/FLAIR hyperintensities in the subcortical white matter of the frontoparietal and occipital lobe. (C): MAG showed no apparent hemorrhage. (D): SWI showed multiple focal T2W/FLAIR hyperintensities in the subcortical white matter of the frontoparietal and occipital lobes.

case_images: MRI revealed bilateral parieto-occipital hyperintensities consistent with vasogenic edema (Figure 1A,B). MR angiography excluded venous sinus thrombosis and vascular spasm (Figure 1C,D).
case_images: CT brain (A): CT BRAIN showed subarachnoid hemorrhage in the right frontal lobe (red arrow) and multiple small petechial parenchymal hemorrhages in the right frontal lobe. (B,C): CT angiogram (arterial and venous) showed no evidence of intracranial aneurysm or vascular malformation and no evidence of cerebral venous sinus thrombosis with hypoplastic left transverse sinus.

case_images: CT imaging after the seizure revealed a right frontal subarachnoid hemorrhage (Figure 2A). CT angiography showed no evidence of aneurysm, vascular malformation, or cerebral venous sinus thrombosis (Figure 2B,C).
case_images: MRI brain (A,B): FLAIR showed multiple focal T2W/FLAIR hyperintensities in the subcortical white matter of the frontoparietal and occipital lobes and evidence of recent right frontal subarachnoid and petechial hemorrhage. (C): MAG showed right frontal subarachnoid hemorrhage (red arrow). (D): SWI showed multiple focal T2W/FLAIR hyperintensities in the subcortical white matter of the frontoparietal and occipital lobes and recent right frontal subarachnoid and petechial hemorrhage.

case_images: MRI confirmed the presence of vasogenic edema and a right frontal SAH (Figure 3A-D).
