Two patients with unusual findings of renal angiomyolipoma (AML) were reported. One had intratumoral giant pseudoaneurysm with mural thrombus and hemorrhage, the other had intrarenal and perirenal hemorrhage, due to vascular malformation, rupture of small aneurysms and pseudoaneurysms within the tumor. Since imaging techniques such as CT, ultrasonography, MRI are being so commonly used, the detectability of renal AML is increased. Understanding of the various composition of renal AML and their accompanied pathology is most helpful in improving the accuracy of imaging diagnoses.
报告了两名肾血管平滑肌脂肪瘤（AML）有异常表现的患者。一名患者的肿瘤内有巨大假性动脉瘤伴壁血栓形成和出血，另一名患者因血管畸形、肿瘤内小动脉瘤和假性动脉瘤破裂而出现肾内和肾周出血。由于CT、超声、MRI等成像技术的广泛应用，肾AML的检出率有所提高。了解肾AML的各种组成及其伴随的病理情况，对提高成像诊断的准确性非常有帮助。
