摘  要:目的 探讨胸膜孤立性纤维瘤(SFTP)的CT表现和病理特点,提高对该病的诊断水平。方法 回顾分析12例经手术病理确诊SFTP的CT表现,并与病理结果相对照。结果 12例SFTP表现为胸腔内软组织影,边界光整,与胸膜呈宽基底相连。其中4例呈丘状、蕈伞状,3例呈类圆形或椭圆形,2例形态不规则沿间隙塑形生长,3例肿块巨大充满一侧胸腔,呈“铸形”改变,9例可见“胸膜尾征”,1例可见“胸膜蒂”形成。CT平扫7例密度均匀, 4例呈高低混杂密度影,1例瘤内见钙化影。增强后5例呈“地图样”不均匀强化及渐进性强化。4例病灶内及边缘见条状、扭曲的血管影。结论 SFTP的CT表现具有宽基底、塑形生长及胸膜尾征形成等特点,仔细分析CT表现有助于提高诊断的准确性。Objective To investigate the CT manifestations and pathology features of solitary fibrous tumors of the pleural (SFTP) ,to improve diagnostic accuracy of this disease. Methods CT manifestations of 12 cases with SFTP confirmed by surgery were analyzed retrospectively by comparison with the pathological findings.Results The CT images of the 12 cases showed intrathoracic soft tissue shadow with well-defined margin which was widely connected with pleural. There were 4 cases with mound like and mushroom shape, 3 cases with round or oval shape, 2 cases with irregular shape growing into the pleural space, 3 cases with large mass filling unilateral thoracic cavity, 9 cases with pleural tail sign and 1 case with pleural pedicle sign. The plain CT showed homogeneous density in 7 cases, high-low mixed density in 4 cases and with internal calcification in 1 case. After contrast enhancement, 5 cases were map like heterogeneous and progressive enhancement, and 4 cases have strip distorted vessel inside or on the edge of the lesion.Conclusion CT manifestations of SFTP have certain characteristics, such as broad base, shaping growth and pleural tail sign, which could be helpful to improve the diagnostic accuracy of SFTP by analyzing carefully.
