Gastroduodenal artery (GDA) pseudoaneurysms are rare clinical entities that typically develop in the setting of chronic inflammation of the pancreas, although idiopathic pseudoaneurysms can occur. Although GDA pseudoaneurysms carry the risk of rupture with resultant hemorrhage, they seldom are reported to cause biliary obstruction. We report a unique case of biliary obstruction secondary to extrinsic compression of the bile duct by a GDA pseudoaneurysm successfully managed by nonoperative means.
