ABSTRACT
A 68 year old man was hospitalized for pulmonary embolism. A month ago, he had a myocardial infarction and 10 days ago he was treated surgically by triple coronary artery bypass grafting. His personal medical and surgical history includes hypertension, appendectomy for appendicitis 50 years ago and exploratory laparotomy for obstructive ileus clue to adhesions 5 years ago. He has no family history for malignancy. Abdominal CT and MRI performed for causative evaluation of the pulmonary embolism, revealed a 5 cm large solid mass of the mesenteric root with clear smooth margins and inhomogeneous density. The mesentcric vessels were not infiltrated. The patient did not mention any gastroenterologic disorders [vomiting, blood loss and defacation problems] and had no abnormal signs on physical examination. The performed coloscopy was negative. The surgical specimen was a solid, hard, well defined retroperitoneal tumor lying in front of the superior mesenteric artery and the left renal vein [Figures 1 and 2]
