This concept is important because elevated intracranial pressure without an intracranial mass or ventriculomegaly is a commonly tested but often overlooked mechanism. It emphasizes how impaired CSF resorption due to cerebral venous sinus congestion (from conditions like idiopathic intracranial hypertension or cerebral venous sinus thrombosis) leads to increased ICP. This is crucial because 38% of test-takers mistakenly answered "increased CSF production", highlighting a common misunderstanding that this flashcard aims to correct.
The flashcard is formatted to match the deck’s style and is properly tagged for easy review. I'd love for you to consider adding it to the deck to enhance its completeness.

see comment section but the text is copy/paste from UWorld learning objective so can't use because of plagarism. Also, the exact pathophys behind IIH is not fully known so don't think we should add a card to define the pathophys - incrased central venous pressure is just one of the theroies according to UpToDate, and this mechanism is not listed in Amboss
