CT scan findings.. Notes: (A) Contrast-enhanced CT scan shows a hyperdense rounded lesion, of 16 mm at its greatest diameter (arrow), in the inferior third of the right kidney, compatible with a posttraumatic pseudoaneurysm. (B) CT scan shows a 3 cm laceration and a perirenal hematoma in the posteroinferior third of the right kidney (arrow).. Abbreviation: CT, computed tomography.

During the arterial phase, the inferior third of the right renal parenchyma showed a hyperdense rounded lesion, of 16 mm at its greatest diameter, suggesting a posttraumatic RAP (Figure 1A). Finally, there was also a posteroinferior right perirenal hematoma, measuring 55x55x37 mm (Figure 1B).
Right renal artery arteriogram findings.. Notes: (A) Ventral and dorsal branches of the right renal artery selective angiogram revealed a mesorenal pseudoaneurysm, of 16 mm at its greatest diameter (arrow), from two interlobar branches of the posterior division of the right renal artery. (B) Superselective embolization of two interlobar branches of the posterior division of the right renal artery was performed, and postembolization images confirmed complete pseudoaneurysm devascularization and preservation of the remaining renal vasculature.

It also showed a RAP, of 16 mm diameter, from two interlobar branches of the posterior division of the right renal artery (Figure 2A). Postembolization images confirmed the complete pseudoaneurysm devascularization, exclusion of other arterial afferents, and preservation of the remaining renal vasculature (Figure 2B).
