目的探讨孤立性纤维瘤 (solitary fibrours tumors，SFT)CT表 现及病理学特征。方法 通过回顾性分析 我院2006年3月-2013年12月经手术病理 证实的8例孤立性纤维瘤CT表现并复习文 献，总结其CT影像特征。结果 MSCT上表 现为孤立、边界清楚的单发肿块。CT平扫 常表现为均匀的低密度肿块，增强多轻中 度强化；肿瘤较大时，常因内部囊变、坏 死呈不均匀低密度，强化多呈不均匀地图 样强化。结论 MSCT可清晰显示SFT病灶的 形态、大小及其周围组织的关系，对SFT 的诊断和鉴别诊断具有一定的帮助。

Objective To explore the solitary fibrous tumor (solitary fibrours tumors, SFT) CT manifestation and pathological features. Methods A retrospective analysis of our hospital from March 2006 to December 2013 menstrual operation and pathology confirmed 8 cases of solitary fibrous tumor CT expression and review of the literature, summarized the features of CT. Results MSCT showed solitary, boundary clear single mass. CT scan showed low density mass uniform, enhanced multiple mild to moderate enhancement; larger tumors, cystic degeneration, necrosis of not uniform in low density, the map like enhancement was not uniform. Conclusion MSCT can clearly show the relationship between the shape, size and surrounding tissues of SFT lesions, has certain help in the diagnosis and differential diagnosis of SFT.
