【摘要】：目的探讨胸膜孤立性纤维瘤(SFT)的CT影像特征,提高诊断及鉴别诊断能力。方法收集15例胸部SFT的CT及临床资料,回顾性分析病变部位、直径、轮廓、密度、强化方式、供应动脉及与周围组织关系。结果 15例均表现为胸腔单发实性肿块。位于左胸5例,右胸7例,纵隔3例。直径2.2~13.6 cm(平均5.5 cm)。9例边缘清楚,6例边缘不清,呈类圆形或不规则形。CT平扫5例密度均匀,10例密度不均,部分可见钙化及坏死。肿瘤呈斑片状或线条状不均匀强化:2例轻度强化,5例速升缓降,8例持续强化。胸廓内动脉,支气管动脉或腹腔干等均可参与供血,未见肺静脉供血。结论 CT可以直观显示胸膜SFT生长特征,在对胸腔内单一血供丰富、进行性不均匀强化的软组织肿块进行鉴别诊断时应考虑SFT可能。
[Abstract]:Objective to investigate the CT imaging features of solitary pleural fibroma (SFT) and to improve the ability of diagnosis and differential diagnosis. Methods the CT and clinical data of 15 cases of chest SFT were collected and analyzed retrospectively. The lesion location, diameter, contour, density, enhancement mode, supply artery and its relationship with surrounding tissues were analyzed retrospectively. Results all the 15 cases showed solitary solid mass in thoracic cavity. 5 cases were located in the left chest, 7 cases in the right chest and 3 cases in the mediastinum. The diameter of 2.2 ~ 13.6 cm (mean 5. 5 cm) was clear in 6 cases with clear margin and irregular or round shape in 5 cases. The density was uneven in 10 cases. Calcification and necrosis were observed in some cases. The tumor showed patchy or linear uneven enhancement in 2 cases, mild enhancement in 5 cases, rapid rise and slow decrease in 8 cases. The internal thoracic artery, bronchial artery or celiac trunk were all involved in the blood supply, but no pulmonary vein was found. Conclusion CT can visualize the characteristics of pleural SFT growth. SFT may be considered in the differential diagnosis of soft tissue masses with abundant blood supply and progressive heterogeneous enhancement in the pleural cavity.
