Gastroduodenal artery (GDA) aneurysm is a rare but potentially fatal vascular disease, with chronic pancreatitis being reported as the commonest aetiological factor. Its main complication is rupture, which is not uncommon and carries high risk of mortality. Clinical suspicion and advanced imaging tools should be employed in a timely fashion to make a diagnosis before this ominous event. We report a case of successfully treated GDA aneurysm who presented with minor bleeding episodes before suffering a major bleed and briefly discuss this pathology in light of the existing literature.
