胸膜孤立性纤维性肿瘤临床病理学及影像学表现

摘要

目的:探讨研究胸膜孤立性纤维性肿瘤(SFTP)的临床病理学特征、影像学表现以及治疗效果.方法:将18例资料完整的胸膜孤立性纤维性肿瘤患者作为研究对象,对其临床病理学及影像学表现进行分析.结果:12例CT平扫后7例显示胸腔有巨大软组织肿块存在,5例表现为胸壁宽基底软组织肿块.6例行MRI检查,MRI信号的改变与病理组织成分密切相关,对组织特征的判断明显优于CT扫面.18例患者分别行胸肿块切除术、电视胸腔镜VAT肿块切除术、电视胸腔镜VAT辅助小切口肿块切除术,均治愈出院.结论:SFTP在胸部呈孤立性肿块,CT及MRI表现均有一定特点;病理学上则表现为肿瘤细胞密度显著增加,细胞核异型性明显.MRI检查对患者的定性诊断有较大帮助.外科手术切除是临床治疗SFTP的首要治疗方法.%Objective:To observe the pathology character, imaging manifestions and curing effect for pleural solitary fibrous tumor. Methods: Eighteen patients with complete medical records were retrospectively analyzed, their clinical treatment and nursing information had been researched. Results: Twelve patients were carried out CT plain scan, large mass with well- defined margin was detected in 7 patients, 5 patients with wide base connected to the pleura. Six cases were given MIR examination. Chest tumor incision, VAT incision and combined incision method has been used. Conclusions: SFTP is independent of solitary tumor in the chest, There are certain features of CT and MRI. Pathology showes a significant increase in tumor cell density, nuclear atypia. CT and MRI examination will be helpful for diagnosis, and MRI signal will be more precise for tissue feature than CT scan. Surgical resection remains the primary clinical treatment for SFTP.
