Abstract
Background: Papilloedema has several aetiologies, including brain tumours, central nervous system inflammation, cerebral venous thrombosis, cerebral venous sinus thrombosis (CVST), and idiopathic intracranial hypertension. CVST is a rare condition and a form of stroke with an incidence of 5:1,000,000/year. Case presentation: A 23-year-old female developed impaired vision in her left eye, accompanied by headache, nausea, and vomiting, 5 weeks prior to hospitalization. Visual acuity in the left eye (OS) was 6/12, which improved to 6/9 on pinhole examination, and to 6/6 with S-0.50 and C-0.50 on the 180° axis. OS intraocular pressure (IOP) was 14 mmHg. Bilateral funduscopic examination revealed papilloedema, peripapillary venous tortuosity, and macular exudate. Both computerised tomography scan and magnetic resonance angiography examination detected superior sagittal sinus thrombosis. Conclusion: Acute CVST is a rare condition. A good prognosis depends on early diagnosis and prompt treatment.
