Abstract：Objective To summarize the experience in the diagnosis and treatment of thalamic dementia caused by dural arteriovenous fistula(DAVF).Methods A retrospective analysis was performed on the data of a 41-year-old female case diagnosed with Borden Ⅲ or Cognard Ⅳ DAVF through cerebral angiography,especially the MRI follow-up during the disease course.Results The clinical manifestations were rapid progressive cognitive impairment,with cranial MRI indicating abnormal signals in the bilateral thalamus.After receiving transarterial embolization treatment,the fistula was completely embolized,and subsequent cognitive function and thalamic abnormalities were significantly improved.After half a year of postoperative follow-up,the patient resumed daily work.Conclusion Continuous cranial MRI examination from asymptomatic progression to dementia,suggests continuous dilation of the great cerebral vein,providing new clinical evidence for elucidating the course of DAVF.
