Visceral pseudoaneurysms (PSAs) are important vascular lesions with high morbidity and mortality if complicated by rupture.  These vascular lesions may form from numerous etiologies, which themselves are associated with considerable morbidity and mortality (e.g. penetrating trauma, pancreatitis). The purpose of this educational exhibit is to review visceral pseudoaneurysms and aneurysms, from the clinical presentation to CT imaging appearance, and discuss management algorithms.
