[Efficacy of modern imaging technics in the diagnosis of isolated angiomyolipoma of the kidney. Apropos of 11 cases].

Ultrasound and computed tomography imaging techniques are very reliable methods of detection and diagnosis of renal angiomyolipoma not associated with the tuberous sclerosis of Bourneville's disease: results are considerably improved when compared with conventional investigations (IVU, arteriography). The series reported included 6 patients with large angiomyolipomas and 5 with lesions less than 2 cm in diameter discovered fortuitously on ultrasonography: all tumors were partially or totally hyperechogenic. The fatty tissue was detected in 9 of the 11 cases by computed tomography imaging.
