Angiomyolipoma (AML) is the most common benign mesenchymal tumor of the kidney. Currently, with advances in diagnostic imaging and widespread application of ultrasound and computed tomography, the accidental diagnosis of asymptomatic AML is increasingly common. retroperitoneal bleeding secondary to AML rupture can be serious and life - threatening. Treatment of such complication includes conservative treatment, total or partial nephrectomy, renal artery embolization... Today, renal artery embolization is recommended as the first choice for AML bleeding and is increasingly being used for the prophylaxis of AML at risk of bleeding.We present a 40 - year - old female patient was admitted to the emergency room with sudden right flank pain, found to have a ruptured right AML causing a perirenal hematoma and treated with selective renal artery embolization. Twelve days after the operation, the patient was stable and discharged from the hospital. Follow-up abdominal CT scan at 1 - and 4 - month intervals showed a marked decrease in tumor size.
