case_images: (a) Axial FLAIR images revealed a hyperintense lesion on the left frontal cortex. (b) Axial T2-weighted image showed a hyperintense lesion on the left frontal cortex. (c) Axial susceptibility weighted imaging revealed thickening and dilation of cortical veins. (d) Sagittal T1-weighted image showed thrombosis of the superior sagittal sinus. (e) Coronal T1 with gadolinium image. (f) Sagittal MRV revealed superior sagittal sinus thrombosis.. MRV: magnetic resonance venography.

case_images: MRI revealed hyperintensities in the left frontal lobe cortex on fluid attenuated inversion recovery (FLAIR) and T2-weighted image, a dilation and thickening of subcortical veins caused by venous thrombosis on susceptibility weighted imaging. Magnetic resonance angiography of the cerebral arterial vessels were unremarkable, while MRV detected superior sagittal sinus thrombosis (Figure 1).
case_images: CT perfusion revealed perfusion deficits of the left frontal cortex. (a) Normal cerebral blood volume (CBV), (b) decreased cerebral blood flow (CBF), (c) delayed mean transit time, and (d) delayed time to peak.. CT: computerized tomography.
