The most frequent causes of acute upper digestive tract hemorrhage are gastroduodenal ulcers, esophageal varices and gastric erosions. Esogastric cancers, angiodysplasias and Mallory-Weiss syndromes can also become complicated by significant digestive bleedings. Much rarer is the intragastric rupture of a splenic artery aneurysm that induces a cataclysmic upper gastrointestinal hemorrhage. We present such an entity, whose exceptional peculiarity is to be associated with a pancreatic adenocarcinoma.

Primary aortic thrombosis remains a rare entity that can be defined as clotting of the vessel without any obvious atheromatous lesion. Cancer chemotherapy, cocaine intake, essential thrombocythemia, some hypercoagulable states, heparin-induced thrombocytopenia, inflammatory disease of the digestive tract and acute pancreatitis are, beside some cases of rather unknown etiology, the causes of primary aortic thrombosis. Intravenous contrast-enhanced multislice CT, which is widely available, noninvasive and affordable in terms of cost, is the imaging modality of choice for the investigation of primary aortic thrombosis and the assessment of potential complications. Three cases due to chemotherapy, antiphospholipid syndrome and acute pancreatitis are reported.
