Splenic artery pseudoaneurysm presenting with massive rectal bleeding

Abstract

Splenic artery pseudoaneursym is relatively rare and its rupture is usually fatal. We report a case of a 48-year-old male with 2 prior episodes of alcoholic pancreatitis that presented with massive per rectal bleeding from rupture of a splenic artery pseudoaneurysm into the transverse colon. Gold standard of diagnosis is CT angiography of the abdomen. We present the first case in the literature where a diagnosis has been made with noncontrast CT of the abdomen and described the radiologic features that facilitated this diagnosis.
