Child, renal trauma. (a) Baseline ultrasonography shows only a fine cortical parenchymal inhomogeneity of the left kidney with perirenal fluid collection; (b) contrast-enhanced ultrasound shows a large renal fracture and highlights very well the presence of perirenal fluid (arrowheads); (c) axial CT scan in the venous phase demonstrates the renal fracture and confirms the perirenal fluid; (d) axial CT scan in the late phase shows the iodinated urine leakage (white arrows) in the perirenal space (urinoma).
