Abstract: Objective To explore the application value of multislice spiral CT in typical renal angiomyolipoma. Methods A retrospective analysis of clinical and imaging data of 24 patients with classic type renal angiomyolipoma diagnosed by CT. Results Of all the 24 patients,5 patients were male,19 patients were female. Single lesion in 19 cases, multi-ple lesions within the single kidney in 2 cases, each kidney had a lesion in 1 case, multiple lesions in the both kid-neys in 2 cases. The numbers in the multiple lesions5~13. The lesions were round,oval or irregular in shape, 14 le-sions in 8 cases were protruding from the renal capsule outline, the residual lesions were located in the renal parenchyma.Size0.4 cmí0.3 cm~6.7 cmí5.9 cm. Unenhanced CT showed the lesions were rich in fat(CT value-106 HU~-10 HU),and more with streaks and soft tissue density. 3 cases underwent enhanced CT,which showed heteroge-neous enhancemen in the substantive component of the lesions. Conclusion CT is easy to demonstrate gross fat within the angiomyolipoma,and can be used for regular imaging follow-up and preoperative evaluation.
