ABSTRACT
INTRODUCTION AND IMPORTANCE: Intraparenchymal renal artery aneurysms are a really rare condition that represents <10 % of all renal artery aneurysms. They are more often caused by trauma or iatrogenic injury and their rupture can lead to life-threatening hemorrhage. CASE PRESENTATION: We report the case of a 25-year-old male with history of back stab wound three months before being admitted to our unity. The patient presented a macroscopic hematuria three days after the injury. An abdominal CT angiography revealed an intraparenchymal renal artery aneurysm, and it was successfully treated with super selective endovascular coil embolization, achieving both pseudoaneurysm exclusion and renal preservation. CLINICAL DISCUSSION: Intraparenchymal renal artery aneurysms are rare. They are more often caused by trauma or iatrogenic injury. Renal artery pseudoaneurysms are mainly asymptomatic. Renal pseudoaneurysms can be diagnosed through contrast enhanced CT, renal Doppler ultrasound, or MRI. Super selective embolization of the feeding artery of the pseudoaneurysm using endovascular techniques is the treatment of choice. CONCLUSION: The management of patients with renal pseudo aneurysms should allow to achieve two main goals: Preserving Renal function, and excluding the pseudoaneurysm.
