Is imaging confirmatory?CTV or MRV confirms CVST

Data is taken from this pathway's reviewed node text. Work through the pathway step by step.

Step 1 / 1 · Is imaging confirmatory?

Suspected CVST — is imaging confirmatory?

💡 Dural sinus/cerebral vein thrombosis → impaired venous outflow, raised ICP, venous infarction/hemorrhage. Headache is most common (isolated headache → focal deficit/seizure/papilledema/coma), can mimic stroke/SAH/tumor. Risk: thrombophilia, pregnancy/puerperium/oral contraceptives, malignancy, infection (otitis/mastoiditis/sinusitis — septic), dehydration. NCCT is often normal (dense thrombus/cord sign in only ~1/3, do not rely on it alone).

For teaching. Decisions and their basis are taken from this site's reviewed care pathways; for licensed clinicians/trainees, this does not replace clinical judgment or local protocols.
