DVST are frequently caused by infections in the skull base, dehydration, thrombophilia, meningioma, and other dural tumours. [3]
The sinuses can be injured by trauma in which damage to the dura mater, may result in blood clot formation (thrombosis) within the dural sinuses. Other common causes of dural sinus thrombosis include tracking of infection through the ophthalmic vein in orbital cellulitis .
