A 65-year-old man presented with epigastric pain. A CT scan carried out at admission demonstrated a large 10.5 cm mass in the right lower abdomen, which moved to the left upper abdomen on a MRI scan carried out 11 days later. The patient had a negative diagnostic laparotomy one year earlier for the same symptoms. He was initially planned for a percutaneous biopsy of the mass, however, had an emergency laparotomy due to massive hematochezia which found a large mesenteric tumor adherent to the proximal jejunum. Histopathology results confirmed an extra-gastrointestinal stromal tumor in the mesentery of the small intestine.
