Аннотация
In this report, we are describing a rare case of dural arteriovenous fistula(DAVF)followed by an isolated symptom of bilateral visual acuity disturbance. The patient was a 67-year-old man suffering from progressive bilateral visual acuity disturbance. Angiography revealed a diffuse arteriovenous fistula in the left transverse-sigmoid sinus affected by severe venous congestion. Visual acuity disturbance is likely to have been caused by increased intracranial pressure(IICP). Venous congestion as well as visual acuity were gradually improved following three transarterial embolizations. It is possible that a gradual progression of the clinical condition has caused only visual acuity disturbance without any other IICP symptoms, which is similar to pseudotumor cerebri. Should an unexplained visual acuity loss occur, the case should be investigated by considering DAVF.
