CECT features of renal lymphangiectasia. Coronal view of CECT of kidneys in non-contrast phase (a) and delayed phase (b). In non-contrast phase, the lesions are difficult to be differentiated from renal parenchyma and pelvicalyceal system. In delayed phase (b), the lymphangiectasia (white arrow) can be well differentiated from the enhancing renal parenchyma and pelvicalyceal system. These lesions are hypodense (0–10 Hounsfield unit), non-enhancing, non-communicating and located peri-renal as well as peri-pelvic
