Write answer in between .Q:A 47-year-old woman presents to the emergency department with a fever and a headache. Her symptoms started yesterday and have rapidly progressed. Initially, she was experiencing just a fever and a headache which she was treating with acetaminophen. It rapidly progressed to blurry vision, chills, nausea, and vomiting. The patient has a past medical history of diabetes and hypertension and she is currently taking insulin, metformin, lisinopril, and oral contraceptive pills. Her temperature is 104F 40.0C, blood pressure is 15793 mmHg, pulse is 120min, respirations are 15min, and oxygen saturation is 98 on room air. Upon further inspection, the patient also demonstrates exophthalmos in the affected eye. The patients extraocular movements are notably decreased in the affected eye with reduced vertical and horizontal gaze. The patient also demonstrates decreased sensation near the affected eye in the distribution of V1 and V2. While the patient is in the department waiting for a CT scan, she becomes lethargic and acutely altered. Which of the following is the most likely diagnosis?? A: Acute closed angle glaucoma, B: Brain abscess, C: Cavernous sinus thrombosis, D: Periorbital cellulitis, E: Intracranial hemorrhage,  <response>: This is a clinical case scenario describing a 47-year-old woman with fever, headache, blurry vision, chills, nausea, vomiting, exophthalmos, decreased extraocular movements, and decreased sensation near the affected eye. She has a history of diabetes and hypertension. Her symptoms are acute in onset and rapidly progressive. The question asks to identify the most likely diagnosis based on the clinical presentation.Key findings pointing towards the diagnosis are:- Acute onset fever and headache - Rapid progression with blurry vision, chills, nausea, vomiting - Exophthalmos and decreased extraocular movements in the affected eye- Decreased sensation near the affected eye in V1V2 distribution - Becoming lethargic and acutely alteredThis constellation of symptoms and signs localizes the pathology to the cavernous sinus which contains cranial nerves III, IV, V1, V2 and VI. The rapid progression also makes an infectious etiology likely.Of the choices given, cavernous sinus thrombosis best fits the clinical presentation described.C: Cavernous sinus thrombosis
