目的: 描述肠系膜罕见原发肿瘤的CT 特点。材料与方法: 搜集4 例,其中恶性血管外皮细胞瘤( MHP) 和恶性纤维组织细胞瘤( MFH) 各1 例,神经纤维瘤( NF)2 例,均经手术和病理证实。与手术对照分析这些肿瘤的CT 表现特点。结果: MHP 原发肿瘤不具特征性,肝转移病灶可表现为多发的形态规则、界线清楚的圆形病灶,部分病灶内可见液面,可有双环征。MFH 仅表现为一不规则形软组织肿块。2 例NF 均表现为无痛性的、体积较大的且有明显的偏侧囊变的混合密度性肿块。结论: MHP 肝转移和NF 可能具有一定的CT 表现特征,但仍需获得组织学证实
Objective: To describe the CT features of rare mesenteric primary tumors. Materials and Methods: Four cases were collected, including 1 case of malignant hemangiopericytoma (MHP), 1 case of malignant fibrous histiocytoma (MFH) and 2 cases of neurofibroma (NF). All of them were confirmed by operation and pathology. CT contrasts with surgery were performed to characterize these tumors. Results: MHP primary tumor is not characteristic, liver metastasis lesions can be manifested as multiple rules of the rules, clear circular borderline, some lesions can be seen in the liquid, may have bicyclic signs. MFH showed only an irregular soft tissue mass. Two cases of NF showed painless, bulky and obvious mixed side of the cystic degeneration of the mass. Conclusion: MHP liver metastases and NF may have some CT features, but still need to be confirmed by histology
