Objective To investigate the value and clinical significance of multi-slice spiral computed tomography angiography (MSCTA) in diagnosing true splenic artery aneurysm. Methods Seven patients with splenic artery aneurysm diagnosed by MSCTA between October 2010 and July 2014 were included in this study. Image post-processing technologies such as multi-planar reformation, curved planar reformation, maximum intensity projection and volume rendering technology were introduced. Results All the artery aneurysms were found through image post-processing technologies. There were 9 tumors in the 7 patients with splenic artery aneurysm, among which 1 was at the upper segment of pancreas, 2 at the segment of pancreas, 3 at the anterior segment of pancreas, and 1 (multiple) at the anterior segment of pancreas and anterior of hilus of spleen. The maximum volume of tumor was 60 mm×57 mm×54 mm. One tumor wall had calcification and other 6 cases only displayed tumor wall had varying degrees of "egg-shell" calcification, and mural thrombosis was detected in 3 cases. Conclusions MSCTA is a reliable method to display splenic artery aneurysm. The combination of multiple image post-processing technologies is more helpful in observing the features of tumor body and the internal and external conditions of tumor cavity, which has guiding significance for further clinical treatment.
