Abstract:Objective To study the imaging diagnosis of renal angiomyolipoma. Methods 20 cases (6 males, 14 females, averaging 47.7 years old) of renal angiomyolipoma proved clinically and pathologically underwent CT scan, in which enhanced CT were preformed in 14 cases,US in 20 cases,MRI in 4 cases,DSA in 2 cases. Result Among 20 cases,two cases suffered bilateral renal tumors,and other cases unilateral tumor.In 22 tumors,7 tumors were found in the renal parenchyma and sinus, 15 tumors located in perinepriric fascia.The mean diameter was 9.14cm.20 tumors were irregular in shape. All tumors showed to have fat to some extent, 4 tumors had hemorrhage and two tumors had subcapsular hemorrhage.Invasion of renal vein was found in 3 cases. Conclusion Renal angiomyolipoma can be diagnosed if a renal tumor has fat content.
