胸膜孤立性纤维瘤的X线和CT表现

目的:探讨胸膜孤立性纤维瘤(SFTP)的X线和CT表现,重点分析CT表现。方法:回顾性分析经病理证实的SFTP患者8例,均接受CT平扫和增强检查,其中3例同时接受X线检查。结果:本组8例CT均表现为胸腔单发实性肿块,边缘清晰,密度均匀(2例)或不均匀(6例),6例瘤内有坏死,3例见斑点状和条状钙化影,1例见大片状钙化;增强扫描强化明显,均匀强化(2例)或不均匀强化(6例),4例其间可见异常增粗、迂曲血管影。结论:胸膜孤立性纤维瘤的CT表现有一定特征性,并可清晰显示SFTP病灶的大小、形态及周围组织的关系,为临床定位、定性诊断提供重要帮助。

Radiographic and CT Findings of Solitary Fibrous Tumor of the Pleura

Objective：To investigate the X-ray and CT characteristics of Solitary fibrous tumors of the pleura（SFTP）,especially the CT characteristic.Methods： We analyzed retrospectively 8 patients with SFTP which had been confirmed by pathology,by treating them with plain CT scans and enhanced CT scans,3 of whom accepted X-ray examination at the same time.Results： All the 8 cases showed chest solitary solid tumors with clear margin,evenly density（2 cases）or unevenly density（6 cases）,6 cases showed necrosis in tumors,3 cases showed images of speckle or strip calcification,1 case showed large area of calcification.Intensifying is more obviously in enhanced CT scan,in which 2 cases were evenly intensified,6 cases were unevenly intensified,4 cases appeared with images of abnormal thick and curved blood vessel.Conclusion： The CT images of SFTP share some specific features.They can clearly demonstrate the area,shape of leisions and their relationship with surrounding tissues,which are of great help for clinical location and qualitation diagnosis.
