SACCULAR aneurysms of the abnormal aorta occur infrequently and when they do, they are difficult to distinguish in diagnosis from such conditions as carcinoma of the stomach and hydronephrosis. Three cases are described in this paper of saccular abdominal aneurysms with unusual manifestations. The first one closely simulated a bleeding peptic ulcer; the second one caused renal failure, and the third was recognizable clinically as a ruptured abdominal aneurysm, although an electrocardiogram suggested an anterior coronary occlusion.
The incidence varies in the recorded series of cases of this condition. Osler1 (1905) reported only 16 cases among 1,800 ward admissions at Johns Hopkins Hospital. Bryant2 (1903), in a review of the autopsy material at Guy's Hospital for 50 years, found 325 aneurysms of the abdominal aorta. Earlier writers, Nixon3 (1911), and even some recent authors (Kampmeier,4 1944; Scott,5 1944; Pratt-Thomas,6 1944) stress syphilis as the predominant etiological factor. Estes7 (1950) found
