So there is no characteristic age period at whichrenal aneurism occurs, the relatively greater frequency of cases of spontaneousorigin in middle and advanced life being probalily more apparent than real dueto the fact that this ty|ie prdduces no symjitoms. as a rule, and is only an.

Type.—From a pathological standpoint, renal aneurisms fallinto the same two main divisions as aneurisms of other vessels, viz.: false, inwhich the sac is formed of surrounding tissues which have walled off the bloodextravasated from the ruptured vessel; and true, in which the wall of the sacis formed of arterial walls, one of which at least is unbroken. So there ismuch more uniformity in structure of the wall of the sac in the latter typethan in the former. Thus, as a rule the false aneurisms were large sacscontaining blood and blood clot, situated in the region
