The findings from repeated angiographies in 16 female and 5 male @entity1 with altogether 34 renal @entity438 were studied. The mean interval between the first and last angiography was 35 months. Seven @entity1 had @entity439 . Two to four angiographies were performed in each @entity1 . They showed no change in 28 @entity439 and slight or minimal enlargement, @entity715 or @entity730 in the other 6. The clinical course was uneventful except for severe @entity101 in 3 @entity1 . No @entity397 occurred. Eight @entity1 , of whom 5 had solitary, @entity439 , were operated upon. Pathoanatomically, @entity4267 or secondarily changed @entity4267 was found in 7 of them. Four died of @entity66 having been followed up for 55-204 months (mean 102 months). Nine were alive and symptomless at the end of follow-up 11-195 months (mean 97 months) after the first angiography. The study supports the view that the risk of @entity397 of a @entity8 is very small, and indicates that @entity4267 is common even when the angiography shows solitary, saccular @entity439 only.

Natural history of XXXX elucidated by repeated angiography and pathoanatomical studies.
