ABSTRACT
Coronavirus disease-19 (COVID-19) patients are at an increased risk of cerebral venous sinus thrombosis (CVST). Rapid diagnosis and treatment are vital to ensure a favorable outcome for CVST, so clinicians need to be aware of all its potential presentations. We describe a unique case where transient visual obscurations (TVOs) from papilledema were the presenting symptoms of COVID-19-related CVST. A 43-year-old woman, who had tested positive for severe acute respiratory syndrome coronavirus-2 1 month earlier, developed holocephalic headache, TVOs, and bilateral disc edema. She did not seek medical attention until she developed TVOs. Visual acuity was 20/20 and Humphrey visual field testing showed enlarged blind spots in both eyes. She was diagnosed with papilledema and underwent magnetic resonance imaging and magnetic resonance venography of the brain, which revealed right transverse sinus thrombosis. Lumbar puncture was performed, showing elevated opening pressure and normal cerebrospinal fluid contents. Her optic disc edema resolved and visual function remained normal 6 weeks following warfarin and topiramate therapy. Recanalization of the right transverse sinus occurred after 3 months. Although rare, TVOs are important presenting symptoms of COVID-19-related CVST. Ophthalmologists, who may be the first physicians to assess patients with this presentation, should be aware of TVOs as potential presenting symptoms of CVST, so diagnoses can be made in a timely manner.
