儿童腹部炎性肌纤维母细胞瘤22例CT表现及病理对照

摘要

目的：探讨儿童腹部炎性肌纤维母细胞瘤（IMT）的CT诊断特征。方法回顾性分析2010年1月~2014年10月经手术病理检查确诊的22例儿童腹部IMT患者的CT影像学特征及病理结果。结果肿块多为实性，无钙化，分布于腹部多脏器，包括肝脏、脾脏、胃、膀胱、胆囊、十二指肠及腹腔等。增强扫描可见实性病灶区内有均匀或不均匀的强化，囊实混合性病灶区见不规则、环状或类圆形强化，病灶多与周围组织界限清晰。结论多层螺旋CT可明确显示儿童腹部IMT的病灶大小、部位、范围、周围浸润情况等，结合病理学检查及免疫组织化学检测，可为手术治疗方案的制定提供依据。%Objective To investigate the CT imaging features of children with abdominal IMT (Inflammatory Myofibroblastic Tumor).Methods CT imaging features and pathological results of 22 cases of children who had been pathologically confirmed with abdominal IMT from January 2010 to October 2014 were retrospectively analyzed.Results Most of the tumors were solid without calcification and distributed in the abdominal organs, including the liver, spleen, stomach, gallbladder and duodenum, gastric antrum and peritoneal. The uniform or non-uniform enhancement was revealed in solid lesions through enhanced scanning. While, irregular, annular or circular enhancement was revealed in the mixed areas of cystic and solid lesions. Most of the lesions had clear boundaries with surrounding tissues.Conclusion Multi-slice CT could be used to identify the size, location, scope and surrounding infiltration in children with abdominal IMT. Combination of CT, histopathological examinations and immunohistochemical detection could provide references for selection of treatment solutions.
