Splenic artery pseudoaneurysms are rare.

Clinical presentation

Unlike splenic artery true aneurysms, splenic artery pseudoaneurysms will nearly always present with symptoms ².

Pathology

While they are sometimes grouped under splenic arterial aneurysms, they are distinct entity and are different from true aneurysms of the splenic artery. In contrast to a true aneurysm the pseudoaneurysm wall contains only the intimal and medial layers².

Their size can vary and if larger than 5 cm they are calledgiant splenic artery pseudoaneurysms ³.

Aetiology

They usually occur as a complication of ^1-2:

pancreatitis
trauma
iatrogenic and postoperative causes
peptic ulcer disease (rarely)

In the case of pancreatitis, the pancreatic enzymes are thought to cause a necrotising arteritis with destruction of vessel wall architecture and fragmentation of elastic tissues.
