A MRI and FLAIR T2W images. Cortical and subcortical high T2 signal in the posterior right temporal lobe corresponding to arterial infarct B High T2 signal subcortical in the frontal lobe corresponding to venous infarct C T1W axial view. High subcortical signal due to hemorrhage in venous infarct. D SWI linear low signal corresponding to thrombosed cortical frontal vein. E Axial T1W with gadolinium. Cortical and meningeal enhancement typical of an arterial stroke. F Sagittal T1W with gadolinium. Intrinsic T1 enhanncement of the thrombosed frontal vein and in cortex of the posterior cortical temporal stroke

Magnetic resonance (MR) imaging of the brain and MR angiography were also requested, which showed two subacute infarcts; one in the arterial territory of the right middle cerebral artery, with triangular shape and with cortical enhancement, and the other in the subcortical venous area, associated with thrombosis of the frontal cortical vein of the same side, and hemorrhage (Fig. 1).
A MR with gadolinium. Right transverse and sigmoid sinuses with partial enhancement due to subacute thrombosis. B MR angiography with significant decrease of the venous flow in the right transverse and sigmoid sinuses due to partially recanalized thrombosis

Also, partial recanalization of the transverse sinus and right jugular vein thrombosis were seen (Fig. 2).
