Radio-endoscopic diagnosis of Dieulafoy's lesion in a duodenal diverticulum.

We report the case of a patient with a Dieulafoy lesion within a duodenal diverticulum, showing the radiographic images. In this case the use of radiological techniques was of great help for diagnosis, bearing in mind that bleeding from this lesion may be intermittent and had not been revealed by the first endoscopic procedure. Since strong clinical suspicion persisted of active upper GI bleeding an angio-CT scan was performed, which allowed to orient diagnosis and rule out other causes of bleeding inaccessible to endoscopy.
