摘要
目的探讨良、恶性腹膜后孤立性纤维瘤的CT表现及其鉴别诊断要点。方法回顾性分析38例经术后病理证实的腹膜后孤立性纤维瘤的CT表现,并与病理结果进行对照,利用统计学方法分析良恶性肿瘤的CT特征性表现。结果38例腹膜后孤立性纤维瘤中,良性18例,恶性20例,其中明显坏死囊变(P=0.0434)、边界不清晰(P=0.0265)、肿瘤直径>15 cm(P=0.0354)、出血(P=0.0415)、钙化(P=0.0381)这五种征象对于鉴别恶性腹膜后孤立性纤维瘤具有诊断价值。结论腹膜后孤立性纤维瘤的边界、囊变坏死程度、肿瘤大小、出血和钙化的CT影像学特征对鉴别良恶性有意义,有助于提高术前诊断准确性及指导手术方式的选择。
Objective To discuss the CT diagnostic characteristics through the comparison of CT features and surgical and pathological results of benign and malignant retroperitoneal solitary fibrous tumor.Methods Retrospective case control study was carried out from AugusT2007 to December 2018.The clinical data of 38 cases with retroperitoneal solitary fibrous tumor who had been confirmed by surgery and pathology with complete preoperative CT data was enrolled,and their CT features were compared between the benign group and the malignant group.Results According to the comparative analysis on the CT imaging signs of the retroperitoneal benign and malignant solitary fibrous tumor,there were five signs had diagnostic value,such as necrosis and cystic lesions(P=0.0434),unclear boundary(P=0.0265),tumor diameter>15 cm(P=0.0354),bleeding(P=0.0415)and calcification(P=0.0381).Conclusions The CT imaging features of the boundary,cystic necrosis,tumor size,hemorrhage and calcification of retroperitoneal solitary fibroma are helpful to differentiate benign from malignant,so as to improve the accuracy of preoperative diagnosis and guide the choice of surgical methods.
