胸膜原发性孤立性纤维性肿瘤(SFT)术前确诊甚为困难,作者应用胸腔镜技术对此进行探讨。研究对象源自作者所在医院1985年1月至1998年12月问收治的632例胸部肿瘤病例,其中确诊为SFT5例(0.8％);男1例,女4例;年龄35岁至81岁。影像学检查(X线片、CT、MRI)5例中4例被误诊为肺肿瘤,全组均行经支气管镜活检术,但不能到达肿瘤区,经皮细针穿刺可达病灶,因其活动,难以获取组织学成分。而胸腔镜下4例明确为源自脏层胸膜的蒂形肿
The diagnosis of pleural primary solitary fibrous tumor (SFT) before operation is very difficult. The authors applied thoracoscopic techniques to investigate this. The study subjects originated from 632 cases of thoracic tumors admitted to the hospital where the author was from January 1985 to December 1998. Among them, 5 were diagnosed as SFT (0.8%); 1 male and 4 female; aged 35 to 81 years. Imaging findings (X-ray, CT, and MRI) were misdiagnosed as lung cancer in 4 of 5 cases. All patients underwent biopsy through a bronchoscope but could not reach the tumor area. Percutaneous needle puncture could reach the lesion because of its activity. It is difficult to obtain histological components. The thoracoscopic 4 cases were clearly pedunculated with visceral pleura
