Accessory renal arteries commonly cause vascular anomalies ; however, reports of blunt trauma injuries to these vessels are rare. Herein, we present a case of accessory renal artery injury in a 24-year-old man who sustained an abdominal injury from a piece of wood. Contrast-enhanced computed tomography revealed an inferior pole infarction of the right kidney, a retroperitoneal hematoma spanning zones 1 and 2, and a vessel branching off from the abdominal aorta distal to the main trunk of the right renal artery. Angiography confirmed rupture of the vessel. The patient was diagnosed with accessory renal artery injury, presenting challenges for embolization due to its complexity. Therefore, the central stump was ligated via laparotomy. Accessory renal artery injury should be considered when a retroperitoneal hematoma is detected at a localized site that does not correspond to the renal infarction site, as in the present case. Moreover, revascularization may not always be necessary.
