孤立性纤维瘤(SFT)是一种少见的梭形细胞肿瘤,发病率约2.8/10万~([1]),生长缓慢,好发于组织的浆膜层,如胸膜,发生在肺部的非常少见。由于本病的临床特征以及影像学表现不具特征性,加之发病率低,术前容易误诊。笔者回顾性分析了本院收治的15例肺部SFT患者的CT表现及病理学基础,旨在提高对该病CT表现的认识。1材料与方法1.1临床资料本院2006年1月至2016年1月收治 Solitary fibromatosis (SFT) is a rare spindle cell tumor with a morbidity of about 2.8 / 10 million ~ ([1]), which grows slowly in the serosa of the tissue, such as the pleura, in the lungs Very rare. Because of the clinical features of the disease and imaging features are not characteristic, combined with the low incidence of preoperative misdiagnosis. The author retrospectively analyzed 15 cases of lung SFT patients treated in our hospital CT manifestations and pathology, aimed at improving the understanding of CT manifestations of the disease. 1 Materials and Methods 1.1 Clinical data The hospital from January 2006 to January 2016 were admitted
