Materials and Methods CT data of 23 cases with renal angiomyolipomas confirmed by surgery and pathology were analyzed retrospectively. Results Among 43 lesions of 23 cases, single and multiple lesions were detected in 15 and 8 patients respectively. There were 24 masses less than 2 cm and 19 masses larger than 2. lcm. The largest one was 9.2 cm × 14.5 cm × 13.3 cm. Right kidney was involved in 13 cases and left kidney in 5 cases and bilateral kidney in 5 cases.
