Renal Lymphangiectasia as an Unusual Cause of Perirenal Collections: A Case Report and Literature Review

Abstract

Renal lymphangiectasia (RLM) is a rare condition characterized by dilatation of perirenal, parapelvic or intrarenal lymphatics. We report an unusual case of bilateral RLM in a 20-year-old Malay male who presented with 1 month duration of bilateral flank pain. Bedside ultrasound showed bilateral perinephric collections, which were further confirmed on computer tomography intravenous pyelogram (CT IVP). Other causes of perinephric collections were ruled out based on laboratory and radiological findings, and he was managed conservatively as for RLM with surveillance ultrasound kidneys at 3 to 6 monthly intervals.
