Axial T1
Focal T1 and T2 hyperintense at the left temporal lobe with restricted diffusion demonstrated on DWI corresponds to an area of subacute hemorrhagic infarct. Subtle thin T2 hypointense rim is in keeping with hemosiderin deposition.
MR venography further demonstrates absence flow of the distal superior sagittal, left transverse and left sigmoid sinuses.
Case Discussion
Features are in keeping with extensive cerebral sinus thrombosis involving the distal superior sagittal, left transverse and left sigmoid sinuses, resulting in venous hemorrhagic infarct of the left temporal lobe.
