Dieulefoy Lesion: Angiographic and Photographic Features with Pathologic Correlation

A 3-year-old girl with 1 day of painless, brisk, lower gastrointestinal bleeding required 7 units of blood transfusion. No bleeding source was found on upper gastrointestinal endoscopy. At laparoscopy, the small bowel and colon were distended with blood. No Meckel ’s diverticulum was present nor was a bleeding site identified. Mesenteric angiography showed bleeding in the proximal jejunum (Figs 1 and 2). At laparotomy, injection of methylene blue through a coaxial microcatheter advanced into the jejunal branch supplying the bleeding lesion stained a short segment of eviscerated bowel (Fig 3).
