Aim: The aim of our study was to evaluate the computed tomography (CT) imaging features of splenic artery aneurysm and pseudoaneurysm and to identify the disease conditions related to the same. We also wanted to ascertain any relationship between these associated disease conditions and the imaging features of the aneurysms. Materials and Methods: This retrospective study included patients diagnosed to have splenic artery aneurysms on contrast-enhanced CT examination between January 2001 and January 2016. Data were obtained from the picture archiving and communication system. The size, number, location, morphology, the presence of thrombosis, calcification, and rupture of the aneurysms were evaluated. Results: A total of 45 patients were identified with a mean age of 45 years. Splenic artery aneurysms were idiopathic in 12 (26.6%) patients. In the remaining patients, the main associated disease conditions included pancreatitis 15 (33%), chronic liver disease with portal hypertension 8 (18%), and extrahepatic portal vein obstruction (EHPVO) 6 (13%). Statistically significant findings included the relationship between EHPVO and multiple aneurysms (P = 0.002), chronic liver disease and fusiform aneurysm (P = 0.008), and smaller size of idiopathic aneurysms (P < 0.001). Conclusion: Based on this study, splenic artery aneurysms were associated with a variety of etiologies. The characteristics of the aneurysms such as size, location, and morphology vary with the associated disease conditions. These variations may have implications for the management.
