A 49-year-old woman had abdominal pain and nausea. She had a history of type 2 diabetes mellitus. Her biochemical laboratory findings were normal. On the abdominopelvic ultrasonographic scan, a 5 × 5-cm mass that was regular in shape was found at the left paraovarian region, and gynecologic consultation was warranted. The patient was referred to the general surgery department because a well-circumscribed 5 × 5-cm solid mass just below the umbilicus was found on the abdominopelvic computed tomographic scan (Figure 1). At surgical exploration, a solid and noninvasive mobile mass with the described enlargement was found on the ultrasonographic and computed tomographic scans; it originated at the antimesenteric jejunal wall and was far from the ligament of Treitz at 100 cm distally (Figure 2).
