Which clinical features are associated with cavernous sinus thrombosis?

• A. Elevated intraocular pressure
• B. Fever, headache, periorbital edema, lid erythema
• C. Blurred vision
• D. Eye redness with discharge

Answer: (B)

Cavernous sinus thrombosis is a serious condition that occurs when a blood clot forms in the cavernous sinus, a cavity at the base of the skull through which several cranial nerves and the internal carotid artery pass. The clinical presentation of cavernous sinus thrombosis typically includes a triad of symptoms: fever, headache, and periorbital edema. These features arise due to the infection leading to thrombosis, increased intracranial pressure, and inflammation of the surrounding structures. Fever is indicative of the infectious process that often contributes to the development of the thrombus, while headache is a common symptom due to the pressure effects on the brain and meninges. Periorbital edema occurs as a result of venous stasis and increased hydrostatic pressure in the orbit because of the impaired venous drainage caused by the thrombosis. Lid erythema may be present as well, adding to the inflammatory picture of the condition. While the other symptomatic choices may relate to different ocular or cranial nerve pathologies, the combination of fever, headache, and periorbital edema directly correlates with the pathophysiological processes involved in cavernous sinus thrombosis. Thus, this set of features is characteristic and important in diagnosing
