Dehydration, secondary to lithium-induced nephrogenic diabetes insipidus, was thought to be the cause of a superior sagittal sinus thrombosis in a 30-year-old woman who presented with confusion, papilledema, and a left hemiparesis (336).

Increased ICR and, thus, papilledema have many causes. Any intracranial space-occupying lesion may create increased ICR. Superior sagittal sinus thrombosis, spinal cord tumors with associated elevated CSF protein, spinal cord injuries, and traumatic brain injmy may all cause papilledema. 

Venous outflow function (VOF) A small venous ROI with similar attributes is selected, most commonly at the superior sagittal sinus. With some software packages, selection of an appropriate venous ROI is critical in producing quantitatively accurate perfusion maps, while others are less sensitive to...

About two-thirds of CSF is derived from the choroid plexi (blood-CSF barrier) located in the lateral ventricles and eventually finds its way back into the venous blood through the superior sagittal sinus. The other one-third of the fluid is derived from the brain parenchyma, in part from filtration across the blood-brain barrier (see Figure 1) and in part from...
