RESUMO
We report a rare case of ectopic pancreatic cancer in the mesentery of the jejunum. A 68-year-old man presented with left abdominal pain. Contrast-enhanced abdominal CT revealed a 3-cm tumor in the mesentery near the ligament of Treitz. He had required surgery for gastric cancer 28 years ago;therefore, surgery was scheduled on the suspicion of recurrence/metastasis of gastric cancer or gastrointestinal stromal tumor (GIST) and mesenteric tumors. A tumor was observed in the mesentery of the jejunum of the ligament of Treitz. Histopathology showed a moderately differentiated adenocarcinoma, and it was diagnosed as a primary ductal pancreatic cancer (Heinrich classification, not classifiable).

A 45-year-old female presented at our hospital with a one-day history of upper abdominal pain. Abdominal computed tomography (CT) revealed that the root of the celiac artery was obstructed and that a large hematoma was present in the retroperitoneum. The patient was diagnosed with retroperitoneal hemorrhage associated with the rupture of an inferior pancreaticoduodenal artery aneurysm, which was caused by increased blood flow in the pancreaticoduodenal arterial arcade. Because the patient's general condition was stable, she was managed conservatively and discharged on achieving remission after a month. Follow-up CT revealed spontaneous resolution of the celiac artery obstruction and aneurysm. The celiac artery obstruction in this case was assumed to be caused by segmental arterial mediolysis.
