Acquired Gastric Dieulafoy-Like Lesion due to Aberrant Blood Supply Diverted From the Left Phrenic Artery to an Enlarged Splenule

Abstract

Dieulafoy lesion is an aberrant submucosal vessel that can erode into the overlying tissue leading to hemorrhage. It is a rare but important cause of gastrointestinal bleeding. We present a case of a patient who developed an acquired Dieulafoy lesion 39 years after splenectomy. Abdominal computed tomography showed an aberrant vessel from a branch of the left phrenic artery, coursing through the gastric fundus to supply a splenule. Angiography with embolization of the aberrant vessel resulted in no further bleeding.
