Figure 3. MRI brain including contrast-enhanced MR venography. (A) Axial T1-weighted pre-contrast image shows signal in bilateral transverse sinuses isointense to grey matter. (B) Axial and (C) sagittal T1-weighted post-contrast images confirm filling defects within bilateral transverse sinuses, superior sagittal sinus, and straight sinus. (D) Coronal and (H) sagittal MIP images from MR venography demonstrate extensive thrombosis of the dural venous sinuses extending into the left internal jugular vein. (E) FLAIR image shows small area of cortical and subcortical edema in the right frontal lobe, with presence of microhemorrhages at this site on SWI (F). (G) DWI images show small foci of diffusion restriction within the temporoparietal white matter bilaterally, compatible with acute lacunar infarcts.
