胸膜孤立性纤维瘤CT影像表现(附两例报告)

目的提高对胸膜孤立性纤维瘤CT影像表现的认识。方法报告2例经手术病理证实的胸膜孤立性纤维瘤的CT影像表现,并复习文献。结果2例病变CT影像均表现为右侧胸腔巨大肿块,边界清楚呈分叶状,与胸壁间间隙清楚;密度不均匀,可见斑点状钙化;增强扫描动脉期显示肿块内较多肿瘤血管,实质期肿块不均匀强化呈"地图样";邻近肺组织受压不张,纵隔移位;右侧少量胸腔积液。其中一例伴有右侧第7后肋受压骨质吸收,第7/8肋间孔扩大,肿块向椎管内扩展。结论胸膜孤立性纤维瘤具有相对特征性的CT表现。CT在定位定性诊断方面有重要价值。

CT features of solitary fibroma in pleura(2 cases report)

Objective To identify the computed tomography(CT) features of solitary pleural fibroma.Methods Two cases were reported and relevant reviews were studied retrospectively.Results CT of the two lesions appeared as very large heterogeneous attenuation mass with well-defined margins and lobulated contours.The separation planes between the lesion and the pleural wall was preserved,with dotted intra-tumor calcification.On contrast-enhanced CT,the lesions demonstrated heterogeneous enhancement with "geographic" pattern,and intra-tumor vessels appeared as serpiginous linear-like enhancement.The adjacent lung tissues were depressed,appeared as atelectasis with mediastinal shift.Ipsilateral pleural effusion was seen in both cases.One case showed bone erosion in adjacent ribs,and the mass growed along the enlarged right 7/8 intervertebral foramen and extended into vertebral canal.Conclusion CT appearance of pleural solitary fibroma has characteristic,which was valuable for qualitative diagnosis and CT guiding for biopsy.
