摘要
目的探讨胸膜孤立性纤维瘤的CT表现,以提高对该病的诊断水平。方法收集本院2015年5月~2019年12月间经手术和病理证实的16例胸膜孤立性纤维瘤患者的资料,回顾性分析其影像特点。结果本研究共16例,所有病例均为单发,所有患者胸部CT均表现为位于胸腔内的孤立性软组织密度结节或肿块。肿块边界光滑,病灶周围脂肪间隙清楚,瘤体大小不一,最大者长径14.0 cm,最小者长径约2.8 cm,平均直径7.5±1.8 cm;CT平扫示瘤块呈等或略低密度,7例密度较均匀,9例密度不均匀;增强扫描示,病灶呈不均匀强化,其中6例为轻中度不均匀强化,10例为明显不均匀强化,6例内部见结节斑片状明显强化区域,6例病灶内部见形态不规则的坏死、囊变区;11例病灶动脉期出现迂曲的血管,10例病灶呈现"地图样"强化。结论胸膜孤立性纤维瘤在CT上表现为来自胸膜的宽基底肿物,动脉期病灶内可见迂曲的血管,不均匀"地图样"强化是其特征性表现。
Objective To investigate the CT manifestations of The Pleura Solitary Fibroma Tumor,to improve the diagnosis of the disease.Methods 16 patients who were diagnosed with pleura solitary fibrous tumor testified by surgery and pathology results were selected in the researcher’s hospital from 2015 Sep to 2019 Dec,and the imaging characters were analyzed retrospectively.Results The research selects 16 patients and all the cases showed single lesion,and the CT findings of all the patients selected are solitary nodules or mass with soft tissue density in thoracic cavity,and the nodule has clear edge;and the fat space around the lesion is clear;and the tumor is different in size,the long diameter of the biggest one is 14.0 cm,while the long diameter of the smallest one is 2.8 cm,and the average diameter is 7.5±1.8 cm.The pain CT scan shows that the tumor has the isodensity or slightly lower density,and 7 cases among them are homogenous in density,and 9 cases among them are not homogenous in density;The contrast enhancement CT shows that the lesion is heterogeneously enhanced,6 cases among them are mild to moderate heterogeneously enhanced,and the other 10 cases are obviously heterogeneously enhanced;6 cases among them have nodular,spotty area obviously heterogeneously enhanced in the lesion,and 6 cases among them have irregular necrotic and cystic area;11 cases among them show the roundabout blood vessels in the arterial phase,10 cases among them show map-like enhancement.Conclusion The CT findings of pleura solitary fibrous tumor shows the broad-base mass coming from the pleura,and roundabout blood vessels and map-like enhancement in the lesion in the arterial phase are the characteristic performances.
