Abstract
Renal lymphangiectasia is a very rare benign disorder characterised by dilatation of the perirenal and peripelvic lymphatics. The condition is commonly misdiagnosed for othercystic lesions of the kidney such as polycystic kidneys. The diagnosis can be made with near-certainty if classical imaging findings are recognised. We report a case of bilateral renal lymphangiectasia, diagnosed on ultrasonography and computed tomography based on the typical imaging findings and the laboratory analysis of aspirated fluid. The patient was managed conservatively.
Highlights
Renal lymphangiectasia is a rare benign disorder of the kidneys with dilated perirenal lymphatics caused by non-communication of the perirenal and peripelvic lymphatics with the main lymphatics.[1]
We present a case of bilateral renal lymphangiectasia associated with a right-sided retrocaval ureter with typical ultrasonography (US) and computed tomography (CT) findings
Bilateral renal lymphangiectasia is a rare benign condition that is often mistaken for other forms of cystic disease of the kidney.[2]
Summary
Renal lymphangiectasia is a rare benign disorder of the kidneys with dilated perirenal lymphatics caused by non-communication of the perirenal and peripelvic lymphatics with the main lymphatics.[1] The condition in itself is benign, but is commonly misdiagnosed as other cystic renal diseases and hydronephrosis.[2] Knowledge of this condition and its typical imaging appearances will assist radiologists to arrive at the correct diagnosis and permit appropriate management of the patient. We present a case of bilateral renal lymphangiectasia associated with a right-sided retrocaval ureter with typical ultrasonography (US) and computed tomography (CT) findings. To the best of our knowledge, this is the first reported association of bilateral renal lymphangiectasia with a retrocaval ureter
