Perirenal fluid collections and monoclonal gammopathy

Abstract

We report here a case with secondary polycythaemia, monoclonal gammopathy of undetermined significance and renal lymphangiectasis revealed by renal failure. Renal failure was probably linked to renal compression by fluid collections. Renal lymphangiectasis is a rare but has already been described in the literature. In addition, its association with a monoclonal paraprotein and polycythaemia seems to be a new clinical entity recently reported in only one patient. © 2011 The Author.
