November 2005 - Venous Infarct

Monthly Cases


Diffuse hypointense areas on the T1W images which turn hyperintense on the Proton & T2W images are noted in the left parietal lobe. An area which is predominantly hypointense with a hyperintense rim on all sequences is noted in this lesion (subacute blood). The lumen of the superior sagittal sinus shows a hyperintense signal (no flow on the MRV-images not available) representative of a thrombus in this case.

 On MRI:

                      Diffuse distribution, not conforming to vascular territories (as seen with arterial infarcts).

                     Hemorrhage may be present (20%).

                     May find a lack of the normal flow void within a dural venous sinus (e.g. in the superior sagittal sinus).

                     Gyral/Wedge shaped enhancement (32%).

                     May see intense tentorial enhancement (collateral's/venous stasis).

                     May see dilated transcerebral medullary veins (connecting the superficial cortical veins with the subependymal veins).

                     In the late stage, there will be encephalomalacic changes.
