Splenic artery aneurysm can be true or pseudoaneurysms.( 2 ) The majority of aneurysms is true, and seen among women and presents as important risk factors the astherosclerosis, arterial hypertension, and multiparity – all these factors are described in our case. About 10% of patients with giant arterial aneurysm described in the literature had hepatic cirrhosis and 2.5% portal hypertension( 3 ) such conditions possible constitutes predisposing factors and they were not seen in our patient. In splenic artery pseudoaneurysm the main risk factor is pancreatitis in which pancreatic enzimes can promove desistegration of the arterial wall and, in case of pseudocist, it can establish a fistulae between pancreatitis and the artery( 2 ) – initially suggested in the our case, based on size of the tumor with blood flow in its interior. This hypothesis was ignored because there was no previous history of pancreatic disease, and more accurate computed tomography exam of abdomen revealed a normal pancreas.
