@entity8880 is an uncommon @entity5 . Of 223 @entity703 that were treated at our institution from 1970-1991, 14 (6.2%) were @entity1637 [9 females (65%) and 5 males (35%)]. The highest incidence was observed in the sixth decade (60.7 yrs). @entity5 size range from 2 to 19 cm in diameter (mean = 8.07 cm); 11 (78.5%) were localized in the right kidney, principally in the superior pole. The @entity5 was incidentally discovered in 8 cases (57%); 1 case presented @entity244 ; 1 had a palpable renal mass; 6 had @entity490 . All the @entity5 were confined to the kidney. Thirteen were Robson stage I and 1 stage II. According to the UICC classification, 12 were @entity8034 T3. All @entity5 were N0 M0. @entity1 evaluation included IVP (6), US (12), CT (14) and selective renal arteriography (2). The typical angiographic patterns were not observed in these 2 cases. Concerning the CT findings, in 8 cases (57%) the first diagnosis discarded was that of @entity1358 , although there were also signs suggestive of @entity1637 . Six cases (43%) showed signs indicating @entity1637 as first diagnosis. All @entity1 were submitted to radical nephrectomy, which achieved good results in all cases at 7 months' to 5 years' follow up.
