Contrast-enhanced MRI with MRV and MRA were performed for the above-mentioned patient (Fig. 6). [A, B] Patchy ischemic gyral enhancement was noted after IV contrast administration in T1-WI. [C] Central filling defect (delta sign) was noted in the superior sagittal sinus at the post-contrast coronal T1-WI with MIP reconstruction (red circle). [D] Long segment filling defect was seen at the post-contrast sagittal T1-WI with MIP reconstruction (red square). [E] This was also demonstrated in sagittal MRV reconstruction (red square). [F] MRA revealed attenuation of the lumen of the left M3 at the left Sylvian fissure as well as distal M4 cortical branches (orange arrow) … Final diagnosis was bilateral frontoparietal infarctions sequel to superior sagittal sinus thrombosis with hyper-acute hemorrhagic transformation. Additionally, left M3 and M4 attenuation was reported
