Highly Numerous Post-Traumatic Splenic Pseudoaneurysms

Splenic Pseudoaneurysms (SPA) are a dangerous complication of splenic trauma. Pancreatitis, peptic ulcer disease and iatrogenic reasons are additional possible causes of SPA. They are extremely rare, with only about 200 cases published in the English literature in 2006, and their prevalence is essentially unknown. SPA have a significant risk of rupture and have been documented to be deadly in adulthood if left untreated. SPA can form 1 to 8 days following a traumatic splenic lesion in the setting of trauma and may be undetected on initial imaging.
