目的总结腹部(腹膜腔、腹膜后间隙)良、恶性纤维组织细胞瘤CT表现,评价CT扫描对诊断腹部原发纤维组织细胞瘤的诊断意义。方法对11例经手术病理证实的原发腹腔(包括网膜、系膜、韧带)和腹膜后间隙良、恶性纤维组织细胞瘤CT平扫和增强扫描的影像资料进行分析。肿瘤径线小,占位表现不明显;肿瘤径线大,占位表现明显,相邻器官、肠管、血管移位明显。肿瘤径线的大小与相邻器官、腹壁脂肪间隙结构是否完整对评价肿瘤的良、恶性有重要意义。依原发肿瘤的部位不同CT表现不同。结果11例原发腹腔、腹膜后间隙纤维组织细胞瘤CT定位准确。恶性肿瘤9/11例,良性肿瘤2/11例,CT良、恶性定性诊断正确9/11例。CT表现对组织类型评估正确4/11。结论CT对原发腹腔、腹膜后间隙纤维组织细胞瘤定位诊断较为准确,对判断良、恶性有很大帮助,对肿瘤组织病理类型的评估有一定的限度。
Objective To summarize the CT findings of benign and malignant fibrous histiocytoma in the abdomen (peritoneal cavity and retroperitoneal space) and evaluate the diagnostic value of CT scanning in the diagnosis of primary fibrous histiocytoma in the abdomen. Methods The imaging data of 11 cases of primary abdominal cavity (including omentum, mesangium and ligament) and retroperitoneal space benign and malignant fibrous histiocytoma confirmed by pathology and CT scan and enhanced scan were analyzed. Tumor diameter is small, placeholder performance is not obvious; tumor diameter line, significant performance, adjacent organs, intestine, vascular displacement significantly. The size of the tumor line and the adjacent organs, abdominal fat gap structure is complete evaluation of tumor benign and malignant is of great significance. According to the different parts of the primary tumor showed different CT. Results 11 cases of primary peritoneal and retroperitoneal fibrohistiocytoma clearance accurate positioning. Malignant tumors in 9/11 cases, 2/11 cases of benign tumors, CT benign and malignant qualitative diagnosis of correct 9/11 cases. CT performance assessment of the correct type of organization 4/11. Conclusion CT in the diagnosis of primary peritoneal and retroperitoneal space fibrohistiocytoma more accurate diagnosis of benign and malignant great help to evaluate the histopathological types of tumor has a certain limit.
