A case report of cerebral dural arteriovenous fistula with psychiatric and behavioral abnormalities and progressively worsening bilateral thalamic edema
The clinical and imaging manifestations of the dural arteriovenous fistula(DAVF)located in the great cerebral vein area with progressive bilateral thalamic edema lack specificity and are easily confused with a variety of diseases.The authors reported a case presented with psychiatric and behavioral abnormalities,followed by bilateral thalamic lesions.Initially,the diagnosis was considered as a glioma of the thalamus,encephalitis and straight sinus thrombosis,but the clinical and imaging findings progressively worsened.Through multi-modal imaging examinations,a DAVF in the great cerebral vein territory was finally diagnosed.By reporting the case and reviewing the literature,this paper aimed to explore the clinical manifestations and imaging features of the disease to reduce the incidence of misdiagnosis.
