Renal lymphangiectasia associated with chronic myeloid leukemia.

Renal lymphangiectasia is a rare disorder characterized by dilatation of peripelvic, renal and perirenal lymphatic ducts. The exact etiology is not known. Congenital forms and ac-quired forms have been described. The latter has been attributed to obstruction of draining retro-peritoneal lymphatic ducts caused by either infection, inflammation or any other cause. We des-cribe the rare association of renal lymphangiectasia with chronic myeloid leukemia, which is probably not yet reported in the medical literature.
