The MRI sequences demonstrate:
- Thrombosis of the cerebral venous sinuses mainly the superior sagittal sinus, transverse/sigmoid sinuses, and right jugular vein which appear of high signal on T1WI/FLAIR and iso-to high signal on T2WI (subacute phase) with loss of their signal void on contrast MR venography.
- signs of secondary intracranial hypertension
- enlarged subarachnoid space around the optic nerves
vertical tortuosity of the optic nerves
flattening of the posterior sclera bilaterally
- intraocular protrusion of the optic nerve head
- Partially empty sella turcica
- moderate enlargement of the Meckel cave mainly on the left
