Abstract
Hypercoagulability is a well-described feature of nephrotic syndrome. The risk of developing a venous thrombus is higher at the time of diagnosis or shortly after. The resulting deep vein thrombosis involves the pulmonary, the deep veins of the lower limbs and renal veins, as described in the literature. We present a case of a man in his 20s with background of nephrotic syndrome, diagnosed at an age of 3 years old, with multiple relapses and on maintenance immunosuppression which is unusual, in two respects: First, the site of thrombosis was in the cerebral venous sinus and second, the onset of the thrombotic episode was years after the initial diagnosis. This case report also focuses on the perspective of the patient, who experienced a rare complication after more than two decades of living with the condition. In a literature search with the search words of 'nephrotic syndrome' AND 'cerebral venous thrombosis in adults', written in English and published from 1970 to 2/2021, we could only find a review article including 5 cases and 10 individual case reports, of which there were only 16 number of cerebral sinus venous thrombosis reported.
