Ultrasound images Splenic artery aneurysm (ABDOMEN)
These are rare, although more common than hepatic artery aneurysms. They are only clinically significant if over 2 cm in diameter, when the risk of rupture and fatal haemorrhage is present. Colour and spectral Doppler confirm arterial flow through the aneurysm and help to differentiate it from other possible cystic masses near the splenic hilum, such as pancreatic pseudocysts. They are usually asymptomatic and are associated with pregnancy or liver disease with portal hypertension. Surgical resection or ligation is performed to prevent rupture, although smaller aneurysms may be safely monitored with ultrasound.
Ultrasound images Pseudoaneurysm Pseudoaneurysm in the spleen occurs in a minority of cases following splenic trauma. An echo-free or ‘cystic’ area may be observed, which demonstrates flow on colour Doppler. In rare cases, pseudoaneurysm is also a complication of splenic infarct, inflitration of the spleen by malignancy, inflammatory disease such as pancreatitis, or infection13 and usually occurs in association with non-traumatic splenic rupture.
