CT scan showed a mesenteric mass with no evidence of intestinal obstruction (Figure 1). These findings gave an ambiguous diagnosis of a solid mass in the mesentery (Figure 1).

Intraoperatively, a spheroid-like mass was occupying the mesentery of the jejunum with an intact jejunal wall (Figure 2). The rest of the bowel and the attached pericolic fat were normal (Figure 2).
