Papilloedema and Increased Intracranial Pressure as a Result of Unilateral Jugular Vein Thrombosis

摘要

Intracranial hypertension and papilloedema are known to develop secondary to cerebral sinus or bilateral jugular vein thrombosis. However, in rare cases, unilateral jugular vein thrombosis may lead to increased intracranial pressure and papilloedema with resultant headache and vision changes. We describe a 45-year-old patient with squamous cell carcinoma of the larynx that developed right jugular vein thrombosis after chemoradiation therapy with cetuximab. This was later complicated by intracranial hypertension and papilloedema. The normal cerebral venous drainage, the potential role of chemoradiation therapy on the aetiology of jugular vein thrombosis, and the mechanism of increased intracranial pressure secondary to unilateral jugular vein occlusion are discussed.
