Renal lymphangiectasia, a rare case of perirenal infiltration
Résumé
Renal lymphangiectasia is a bilateral cystic infiltration of the perirenal and parapelvic space which is caused by the obstruction of the renal lymphatic tissue. To our knowledge only numbers have been reported in the literature. Renal lymphangiectasia usually asymptomatic and incidentally diagnosed has absolutely no effect on the patient outcome. Radiological imaging is typical so that the diagnosis does not need to be confirmed by a cyst punction. The lack of knowledge concerning renal lymphangiectasia make it usually confused with another cause of polycystic renal infiltration, such as the polycystic kidney disease. We report herein a case of renal lymphangiectasia diagnosed incidentally by an abdominal ultrasonography.
