Abstract
Dural arteriovenous fistula(dAVF)can cause cerebral vein perfusion disorders and presents with various symptoms. We report a case of dAVF in a 72-year-old man whose visual function was maintained with early treatment. He became aware of transient blurred vision and vascular noise and was referred to our department by a local ophthalmologist for bilateral papillary swelling. His best-corrected visual acuity in both eyes at his first visit was 1.2. He had no abnormalities in either eye, except bilateral papillary swelling. Head magnetic resonance imaging(MRI), magnetic resonance angiography(MRA), and magnetic resonance venography(MRV)findings were suggestive of dAVF of the lateral and sigmoid sinuses. We referred him to the neurosurgery department and he was finally diagnosed with dAVF. Catheter treatment was performed 1 month after the first visit. Postoperatively, there was improvement in the transient blurred vision, vascular noise, and papillary swelling. To identify the cause of bilateral papillary swelling, it is necessary to look for intracranial space-occupying lesions but also intracranial hypertension due to perfusion disorders at an early stage using MRI and intracranial angiography approaches, such as MRA and MRV.
