| 目的 探讨胸膜孤立性纤维瘤(SFTP)的CT表现及MSCT诊断价值。方法 回顾性分析12例经手术病理证实的SFTP患者的临床和CT影像资料,并与病理结果进行对照分析。结果 12例SFTP中,10例为良性,2例为交界性。10例呈类圆形或类椭圆形,2例呈不规则形。12例病灶均呈膨胀性或铸型生长,边界较清。1例肿块造成肋骨轻微压迫性骨吸收,1例病灶局部侵犯胸壁软组织。9例病灶平扫密度不均匀,1例伴多发小结节状钙化。9例增强扫描动脉期呈轻至中度均匀或不均匀强化,7例可见明显强化血管影;静脉期各例呈中度至明显持续渐进性不均匀强化,呈"地图样"改变。5例病灶可见坏死囊变区。结论 SFTP的CT表现具有一定特征性,MSCT重建对其定位和定性诊断具有重要价值。 |

| Objective To explore the CT manifestations of solitary fibrous tumor of the pleura(SFTP) and diagnostic value of MSCT. Methods The clinical information and CT findings were analyzed retrospectively and comparatively with pathological results in 12 patients with SFTP confirmed by pathology. Results In 12 cases, 10 patients with benign SFTP and 2 patients with borderline SFTP were found. The tumors displayed round or oval shape in 10 cases and irregular shape in 2 cases. All tumors showed well-defined margin with expansibility or casting mould. One mass led to slight compression bone resorption of rib. Focal encroachment of chest-wall soft tissue was found in 1 case. The tumors had inhomogeneous density in 9 cases and multiple nodositas calcification in 1 case. During the arterial phase, 9 cases displayed mild to moderate homogeneous or inhomogeneous enhancement, blood vessels with obvious enhancement were seen in 7 cases. All cases demonstrated moderate to obvious continuous progressive enhancement with "geographic pattern" during the venous phase. Five cases were found with necrosis and cystic areas. Conclusion CT appearance of SFTP has certain characteristic features. MSCT reconstruction is of important value for the localization and qualitative diagnosis of SFTP. |
