Unusual cortical symptoms of dural arteriovenous fistula mimicking transient ischemic attack.

The clinical presentation of dural arteriovenous fistula (DAVF) can vary. A 47-year-old man complained of transient difficulty playing badminton and speech disturbance for 10 minutes. His symptoms were suspected to be visuomotor coordination deficit similar to optic ataxia and anomic aphasia. Magnetic resonance imaging and angiography revealed vasogenic edema and perfusion delay in the left temporo-occipital area and an abnormal connection between the left occipital artery and transverse sinus. Transverse sinus DAVF was diagnosed by conventional cerebral angiography. We believe that this is the unique case of DAVF manifested as visuomotor coordination deficit suspected optic ataxia and anomic aphasia.
