Thromboembolism is one of the most serious complications of nephrotic syndrome (NS). Although the occurrence of renal vein thrombosis or deep vein thrombosis is well recognized in NS patients, they rarely develop cerebral venous thrombosis (CVT). The mortality rate of CVT patients is still approximately 10%, and 6-10% of patients who survive have a severe and permanent disability. Herein, we report the case of a 26-year-old woman with multiple thrombotic risk factors, including the presence of NS, use of oral contraceptives, smoking, and alcohol consumption who developed wide-range CVT. Undetermined fraction heparin, albumin and AT-III transfusion, and direct mechanical catheter thrombectomy were insufficient for the improvement of CVT. However, CVT eventually improved along with the remission of NS by prednisolone administration. This process indicates that in the management of CVT associated with NS, it is crucial to control the activity of NS. Currently, knowledge on the treatment for NS associated with CVT is limited, and this is a subject of urgent investigation.
