摘　　要：目的探讨腹部脏器原发性恶性纤维组织细胞瘤(MFH)的CT影像特征。方法回顾性分析经手术病理证实的4例腹部脏器原发性恶性纤维组织细胞瘤病例的临床、病理资料和CT表现,4例均行CT平扫和增强扫描。结果2例发生于肾脏,1例发生于十二指肠,1例发生于脾脏。肿块呈团块状或分叶状改变,瘤体大合并坏死、囊变,常见瘤内钙化,呈浸润性生长侵犯周围组织,增强扫描呈渐进性或持续性强化方式。结论原发于腹部脏器的恶性纤维组织细胞瘤较罕见,其CT表现无明显特异性,但有一定的影像特征能为该病的诊断提供帮助,但真正确诊依赖于病理和免疫组织化学检查。Objective To discuss the CT imaging features of primary malignant fibrous histiocytoma(MFH)of abdominal organs.Methods The clinical,pathological data and CT manifestations of 4 cases with primary MFH of abdominal organs proved by histopathology were analyzed retrospectively.CT scan and enhanced scan were performed in all 4 cases.Results 2 cases occurred in the kidney,1 case in the duodenum,and 1 case in the spleen.The masses were massive or lobulated,large in size and uneven density,accompanied by cystic necrosis,common calcification,and invasion of adjacent structures,with continuous or progressive enhancement patterns in an enhanced scan.Conclusion The primary MFH of abdominal organs is rare,and its CT manifestation is not specific,but it has certain imaging features.So CT can be helpful for the diagnosis of the disease,but the final diagnosis is confirmed by pathological and immunohistochemical examination.
