【摘要】：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。
[Abstract]:Objective to investigate the CT manifestations of pleural solitary fibroma (SFTP) and the diagnostic value of MSCT. Methods the clinical and CT images of 12 patients with SFTP confirmed by operation and pathology were retrospectively analyzed and compared with the pathological results. Results of the 12 cases of SFTP, 10 were benign and 2 were borderline. 10 cases were round or like ellipse, and 2 were irregular. In 12 cases, the lesions were both expansive or cast, with a clearer boundary. 1 cases of lumps caused slight compression of the ribs and 1 cases of local invasion of the soft tissue of the chest wall. 9 cases were plain uneven density, 1 cases with multiple small nodular calcification. 9 cases of enhanced scan showed mild to moderate homogeneous or heterogeneous enhancement in arterial phase, and 7 cases showed obvious enhancement of vascular shadow. In venous phase, all cases showed moderate to obvious progressive, heterogeneous enhancement, and showed a "map like" change. Necrotic cysts were found in 5 cases. Conclusion the CT performance of SFTP is characteristic, and MSCT reconstruction is of great value for its localization and qualitative diagnosis.
