With the exception of aneurysms of the aorta and iliac segments, splenic artery aneurysms are the most common form of aneurysm found in the abdomen, The pathogenesis of splenic artery aneurysms may be largely congenital, in women, and atherosclerotic, in men. A blunt trauma may be one of the less common causes of splenic artery aneurysms. Furthermore, to our knowledge, the delayed development of a splenic artery aneurysm, after a blunt trauma, is extremely rare. We report a case of a 35-year-old man with the delayed development of a splenic artery aneurysm on a follow-up computed tomographic scan of the spleen, 2 weeks after injury. Our case showed that a follow-up computed tomographic scan, after a blunt trauma, provided valuable clinical information on the diagnosis and management of splenic injury for documentign the healing or the progression of the injury, even though some studies have suggested this has no particular value.
