Renal Lymphangiectasia: A Curious Cause of Pleural Effusion
Renal lymphangiectasia is a disorder of the lymphatic system of the kidneys, which can be congenital or acquired. Although the exact etiology remains unknown, an obstructive process resulting from several causes, including infection, inflammation or malignant infiltration, has been suggested to be responsible for the acquired form. This disorder may be associated with several pathologies. We report a case of a 24-year-old man with renal lymphangiectasia presenting with polycythemia, ascites and pleural effusion associated with hepatitis C virus (HCV) infection in an intravenous (IV) drug user. Our case is the first in the literature that shows an association between HCV infection and IV drug use.
