Some specific causes of TCH can be suggested by different clinical presentations, such as:
- If the TCH occurs repeatedly over days to weeks, it may suggest RCVS.
- If TCH is associated with orthostatic headaches, it may suggest spontaneous intracranial hypotension.
- If TCH occurs in the postpartum setting, it may suggest RCVS or cerebral venous thrombosis.
- If there has been recent minor trauma, it may suggest cervical artery dissection or spontaneous intracranial hypotension.
- If the patient has Horner syndrome or pulsatile tinnitus, it may suggest dissection of the ipsilateral internal carotid artery.
- If the patient presents with papilledema and visual symptoms, it may suggest intracranial hypertension related to cerebral venous thrombosis.
- If the patient has fever or meningismus, it may suggest meningitis.
