An unusual presentation for nephrotic syndrome. Bilateral perirenal subcapsular fluid collection.

Abstract

We present a 30-year-old man with nephrotic syndrome presenting with bilateral perirenal massive collection compatible with transudation. After drainage of collections kidney biopsy was performed and the histologic diagnosis was focal and segmental glomerulosclerosis. The patient was treated with cyclophosphamide, prednisone, furosemide and enalapril. After remission of nephrotic syndrome renal ultrasound showed complete resolution of perirenal collections. In conclusion, the case shows that perirenal subcapsular transudation is a rare complication of nephrotic syndrome and massive collections can be treated successfully by percutaneous drainage.
