Membranous Nephropathy: A Rare Association With Renal Vein Thrombosis

Background: Thromboembolic events are a known complication of nephrotic syndrome and occur with a frequency varying from 10% to 45% depending upon the underlying disease. Case Presentation: A 25 year male presented with history of decreased urine output , groin pain and edema lower limbs. Laboratory tests showed Urea 30mg/dL; Creatinine 0.66mg/dL; albumin 2.3g/dL; proteinuria 3+ and negative viral serology. An abdominal ultrasound with Doppler showed features suggestive of partial revascularization. Renal biopsy showed membranous nephropathy. Conclusion: Our case shows that renal vein thrombosis (RVT) is a complication of membranous nephropathy.
