In a classic review of the literature on splenic artery aneurysms, Owens and Coffey,1 in 1953, included the report of a case diagnosed after translumbar aortography by Evans in 1950. Since then, Berger and associates,2 in 1953, and Downes and others,3 in 1955, have also reported translumbar aortography for diagnosis of splenic artery aneurysms. The advent of an intravenous method of abdominal aortography makes the diagnosis of splenic artery aneurysms relatively simple.4 The purpose of this paper is primarily to report the case of a patient whose calcifications in the left upper quadrant of the abdomen were discovered after roentgenography of the lower part of the spine for backache.
