1 Acute thrombosis of the superior sagittal sinus and cortical veins in a 34-year-old woman with 2 days of lasting headaches and left hemiparesis. Acute thrombosis of the superior sagittal sinus and cortical veins in a 34-year-old woman with 2 days of lasting headaches and left hemiparesis. A, Axial fluid-attenuated inversion recovery (FLAIR) image. B, Axial T2* image. The thrombosis maybe missed on spin-echo sequences because it appears with T1 isointensity (not shown) and T2 FLAIR hypointensity, signal intensities close to normal circulating venous structures. On the other hand, the T2* image obviously demonstrates abnormal magnetic susceptibility effect (MSE) in the thrombosed venous structures and in the right transcerebral veins. F.
