a–f Arterial pseudoaneurysm and artero-venous fistula (lesions not included in the AAST classification). On the 3-mm-thick multiplanar reconstruction (MPR) axial images acquired during the arterial (a and d) and nephrographic (b and e) phases of the study in two different patients, a well-delimited oval lesion (arrowheads in the first patient and arrows in the second one) with a density that varies parallel to the density of the arterial vessels is clearly recognisable. Digital subtraction angiography characterised these lesions as an arterial pseudoaneurysm in the first patient (c) and as an artero-venous fistula in the second one (f) in which an early venous output (arrowheads) was recognisable
