Cerebral edema peaks 36–72h after moderate traumatic brain injury but thought to be uncommon after mild traumatic brain injury. Post-traumatic headache can develop 48–72h post-injury, perhaps reflecting the developing cerebral edema. Pseudotumor cerebri can result from various causes, including ...

Pseudotumor cerebri is characterized by intracranial hypertension unassociated with a space occupying lesion. The pathophysiology of pseudotumor remains controversial. Evidence of primary involvement of the cerebrovascular bed, the brain parenchyma and the cerebrospinal fluid compartment have been postulated....
The pathophysiology of the intracranial hypertension in pseudotumor cerebri is still an unsolved puzzle. Increased resistance to CSF outflow leading to an increased CSF volume (interstitial brain edema) (Johnston and Paterson 1975, Gjerris et al. 1985) and intracellular brain water accumulation (Sahs...
