Mesenteric inflammatory myofibroblastic tumors in an elder patient with early recurrence: A case report

Figure 1 Abdominal CT scan showed a 11 cm heterogeneous mass at the mesentery without bowel involvement.

Figure 2 A multinodular tumor at the mesentery of proximal jejunum, 11 cm × 11 cm × 7 cm in size, with irregular margin was found on laparotomy, the omentum was focally involved.

Figure 3 The surgical specimen showed a tumor 19 cm × 17 cm × 10 cm in size involving the mesentery of both jejunum and ileum.

Figure 4 The saggital section showed that the tumor was well circumscribed, grayish white, and firm with foci of hemorrhage, necrosis, and cystic degeneration.
