Inflammatory myofibroblastic tumor (IMT) of the alimentary tract often occurs in children or young adults, but may occur at any age. Symptoms are nonspecific and depend on the location of the tumor. The most often involved sites are small bowel mesentery especially the distal ileum, mesotransverse colon, or great omentum. Recurrence appears to be more frequent in the extrapulmonary lesion. Herein we demonstrate a 63-year-old male patient with mesenteric IMT, with an early recurrence after his first operation. We should be aware that if the tumor is larger than 8 cm, multinodular, omental, with ill-defined margin, with pathologically atypia, or ganglion-like cells, a close surveillance after primary surgery with image study might be necessary to detect the tumor recurrence early. Tumor recurrence may be asymptomatic, and it may act like a malignant tumor with a poor prognosis.
消化道炎性肌纤维母细胞瘤（IMT）常发生于儿童或年轻人，但可发生于任何年龄。症状无特异性，取决于肿瘤的位置。最常累及的部位是小肠系膜，尤其是回肠末端、横结肠系膜或大网膜。肺外病变的复发似乎更为常见。在此，我们展示了一名63岁患有肠系膜IMT的男性患者，他在首次手术后早期复发。我们应该意识到，如果肿瘤大于8cm、多结节、位于网膜、边界不清、病理上有异型性或有神经节样细胞，初次手术后可能有必要通过影像学检查进行密切监测，以便早期发现肿瘤复发。肿瘤复发可能无症状，且其行为可能类似预后不良的恶性肿瘤。
