Renal lymphangiectasia is a rare diagnosis. It is also referred to as renal lymphangioma, renal lymphangiomatosis, peripelvic lymphangiectasia, renal peripelvic multicystic lymphangiectasia, and hygroma renale. The presentation varies, and the diagnosis depends on accurate radiologic interpretation. We present the radiologic images of a pediatric patient who was diagnosed with renal lymphangiectasia after being evaluated for suspected nonaccidental trauma to emphasize the importance of identifying this entity by the characteristic radiologic findings.
