Contrast study of the duodenum showing an obstructive mass in the inferior horizontal part of the duodenum.

Surgery proved an obstructing duodenal carcinoma with intravenous tumor extension. Because the tumor was irresectable a gastroenterostomy was performed to allow passage of food.

An intraluminal mass in the mesenteric or portal veins can be caused by a venous thrombosis or a tumor thrombus. Color doppler can help in the diagnosis by confirming or excluding flow in the mass.
