Imaging angiomyolipoma of the kidney: nine cases.

Purpose: to report the radiological polymophism of angiomyolipoma (AML), Materiel and methods: a retrospective series of eight cases of AML explored by US and CT scan, The diagnosis was radiological in seven cases and histo pathological in one case. Result: five cases of AML were discovered fortuitously, The tuberous sclero sis of Bourneville disease (TSB) was noted in five cases. The overage age w as 37 years with female predominance noted in seven cases. The AML were mul tiple in half cases all of thein had TSB. The tumoral size ranged from 0.5 cm and 20 cm. The US showed an homogenous hyperechogenique mass in six case s and heterogenous in two cases. The CT scan showed polymorph parenchymal l esions. The fatty component was detected in seven cases, An intratumoral bl eeding was noted in one case. Conclusion: the radiological feature of AML is variable, related to tumoral size. It's typical when a tumor of kidney contains fat. An association wit h TSB is a supplementary argument of diagnosis. (C) 2001 Editions scientifi ques et medicales Elsevier SAS.
