Abstract

Splenic artery pseudoaneurysm (SAP) is a rare entity, which occurs when the arterial wall is composed only of the intima and media mainly caused by pancreatitis, or abdominal trauma. Regardless of size, SAP is a high mortality disease that carries a high risk of rupture, causing abdominal pain and severe pancreatic and gastrointestinal bleeding. Here, we describe a rare case of SAP rupture caused by a large gastric ulcer due to Helicobacter pylori infection and NSAIDs use. Understanding the characteristic enhanced CT images of SAP, the complications of splenic infarction, and the therapeutic efficacy of arterial embolization is essential for the clinician to properly diagnose and treat SAP.
