In this article, we will discuss the Clinical Features of Cerebral Venous Sinus Thrombosis. So, let’s get started.
Sinus involved and clinical features
1. Cavernous sinus thrombosis: Features include Chemosis, proptosis, ptosis, headache, opthalmoplegia (internal and external), papilloedema, retinal hemorrhage and reduced sensation in trigeminal first division. 3rd, 4th and 6th cranial nerves palsy. Involvement is often bilateral and patient is ill with fever, headache, retro-orbital pain and toxemia
2. Superior sagittal sinus: Features include headache, papilloedema, seizures, coma. May involve veins of both hemisphere producing weakness of both legs (paraplegia) or quadriplegia with predominant lower limbs involvement and sensory focal deficits. Other features include fever, stiffness or signs of meningitis if associated with bacterial meningitis.
3. Transverse sinus 6th: Features include headache, earache, hemiparesis, convulsions, papilloedema, Gradinego’s syndrome (retro-orbital pain or facial pain, otitis media and 6th cranial nerve palsy).
4. Jugular foramen or jugular vein: Commonly transverse sinus thrombosis spreads to jugular vein; hence its features may be present. 9th, 10th and 11th cranial nerve palsies.
