就我院经病理证实右半结肠肌纤维母细胞瘤的病例1例，结合患者临床病例资料与相关文献报道进行回顾性诊断分析。

该患者为老年女性，临床表现为腹部肿块，无其他特异性表现，诊断难度大。IMT多发生在儿童及青少年，常见累及器官是肺，右半结肠炎性肌纤维母细胞瘤在临床上罕见。

炎性肌纤维母细胞瘤发病率低，呈低度恶性，临床表现不典型，影像学检查无特异性，易误诊，确诊仍依赖于病理及免疫组化检查。手术为其有效的治疗手段。有复发倾向，术后随访有重要意义。

To improve the understanding, diagnosis and treatment of this disease by the report of this case.

On our hospital pathologically confirmed cases of right hemicolon myofibroblastic tumor in 1 case, combined with the patients clinical data and relevant literature reports were retrospectively analyzed.

The elderly woman patient?s clinical manifestations is abdominal mass, with no other specific manifestations, so the diagnosis is difficult. IMT occurs in children and adolescents, common involved organs is the lung, right-sided colitis myofibroblastic tumor in clinical rare.

The Inflammatory myofibroblastic tumor is a low-grade, with low incidence rate, clinical manifestations of atypical and no specific neuroimaging, so it is easy to be misdiagnosed, and it?s final diagnosis still depends on pathology and immunohistochemistry. Surgery is the effective treatment method. Because of the tendency of recurrence, postoperative follow-up is important.
