Renal Lymphangiectasia. An Unusual Mimicker of Hydronephrosis - A Case Report

Abstract

Renal lymphangiectasia is very rare benign lymphatic malformation of renal lymphatics, characterized by cystic dilatation of perirenal, peripelvic, or intrarenal lymphatic vessels. One of the rare mimickers of hyd- ronephrosis and cystic renal lesions on the imaging findings. We report a case-patient with unilateral right renal lymphangiectasia with flank pain and arterial hy- pertension. The ultrasound examination revealed right kidney hydronephorosis. The renal lymphangiectasia was identified on contrast-enhanced computed tomogra- phy scan. The patient was managed conservatively with antihypertensive drugs. The report also contains a re- view of the literature on the pathophysiology of renal lymphangiectasia, clinical presentation, imaging findings, differentials, complications and treatment.
