Abstract：Objective To report the clinical and typical imaging features of a patient with recurrent cerebral venous thrombosis(CVT)secondary to anemia,and to review the relevant literatures in order to enhance the understanding of recurrent CVT.Methods and Results A 38-year-old female patient initially presented with metamorphopsia and reading difficulties.Laboratory tests revealed significant decrease in hemoglobin and increase in platelet count.MRI and MRV showed thrombosis of the left transverse and sigmoid sinuses.She was diagnosed with CVT with secondary venous infarction and severe anemia.After anticoagulation therapy and treatment to correct the anemia,the condition improved.However,she stopped anticoagulation therapy on her own after 3 months.One year later,she experienced a recurrence of CVT.MRI and MRV showed cortical venous thrombosis.Anticoagulation therapy was restarted,and the symptoms improved.Conclusions In patients with anemia and other hypercoagulable risk factors,CVT should be highly suspected when neurological deficits or epileptic seizures occur.A definitive diagnosis can be made with imaging findings.CVT requires both active etiological treatment and adequate anticoagulation therapy to prevent recurrence.
