[Unusual imaging findings of renal angiomyolipoma with giant pseudoaneurysm and intrarenal perirenal hemorrhage].
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.
