title: [Cerebral venous thrombosis in minimal change nephrotic syndrome].
abstract: A 46-year old man presented with an eight-day history of edema and was found to be nephrotic, with a plasma albumin level of 1.1 g/dl and urine protein excretion of 13.3 g/24 hrs. The level of plasma creatinine was normal at 1.0 mg/dl. A finding of renal biopsy was consistent with minimal change glomerulopathy. On the 6th hospital day, he suddenly developed a severe headache and was noted to have bilateral papilledema. Lumbar puncture revealed an opening pressure of 250 mm of water. Magnetic resonance venography showed an irregular flow in the superior sagittal sinus and right transverse sinus, a finding consistent with thrombus. The diagnosis of cerebral venous thrombosis was made, and the patient was given both Warfarin 2 mg/day and prednisolone 60 mg/day. A complete recovery from nephrotic syndrome was achieved within eight weeks. Nephrotic syndrome causes a hypercoagulable state, leading to both venous and arterial thrombosis. The most common clinical features are renal vein thrombosis, femoral vein thrombosis, and pulmonary embolism, however, cerebral venous sinus thrombosis is rare in patients with nephrotic syndrome. It is important to be aware of this complication, since prompt treatment with anticoagulation and control of nephrotic syndrome can lead to a successful outcome.
