摘　　要：目的探讨胸膜孤立性纤维瘤（PSFT）的MSCT特征及应用价值。方法回顾性分析7例经手术病理证实的PSFT的MSCT资料。结果7例均表现为胸腔内边缘光滑的孤立肿块,1例肝脏多发转移。6例平扫密度均匀,1例不均匀。增强扫描不均匀强化,内见弯曲肿瘤血管,1例见周围侧枝开放。6例见＂假包膜征＂,4例见＂胸膜尾征＂或＂胸膜蒂＂。结论MSCT的多平面重组技术可显示PSFT与胸膜的关系,为其诊断提供了重要的信息。Abstract：Objective To explore the MSCT characters of pleural solitary fibrous tumor and the diagnostic value of MSCT. Methotis MSCT manifestations of pleural solitary fibrous tumors in 7 cases proved by surgery and pathology were retrospectively analyzed. Results All cases appeared as solitary well--circumscribed masses in the thoracic cavity. 1 case had metastasis in liver. On the pre--contrast imaging, the density of tumors was homogeneous in 6 cases. On the post--contrast, non--homogeneous obvious enhancement was displayed and distorted vessels could be seen. Some collateral vessels were revealed in 1 case. Pseudocapsules were revealed in 6 cases and “pleural tail sign” or “pleural pedieled sign”revealed in 4 cases. Conclusion MSCT can reveal the relationship between pleura and pleural solitary fibrous tumors, that is helpful for diagnosis.
