| 【摘要】目的：探讨系统性硬化症（SSc）胸部异常改变的MSCT及HRCT表现。方法：回顾性分析60例经临床证实的SSc患者的临床资料，所有患者行MSCT扫描，并对患者肺部主动脉弓层面、气管隆突层面及肺底行HRCT扫描，观察其影像学表现。结果：8例患者肺部未见明显异常，52例均表现为不同程度的肺间质改变。CT表现：小叶间隔增厚（52例，86.7%）；胸膜下弧形线（52例，86.7%）；磨玻璃密度影（26例，43.3%）；网格样影（45例，75.0%）；灶周肺气肿（48例，80.0%）；牵拉支气管扩张（9例，15.0%）；蜂窝征（19例，31.7%）。12例合并肺气肿，9例合并肺心病，3例合并陈旧性肺结核，1例合并真菌感染，1例合并周围型肺癌。结论：结合临床资料并仔细分析SSc胸部异常改变的MSCT及HRCT表现，有助于提高该病诊断与鉴别诊断水平。 |
| 【Abstract】Objective:To study the pulmonary abnormalities in systemic sclerosis (SSc) by multi-slice CT (MSCT) and high resolution CT (HRCT).Methods:The clinical materials of 60 patients with clinically proven SSc were analyzed retrospectively.All patients had MSCT,and HRCT images at the level of aortic arch,tracheal carina and lung base were acquired,the imaging findings were studied.Results:No obvious pulmonary abnormality could be revealed in 8 patients;various degree of pulmonary interstitial changes could be seen in 52 patients.CT findings included interlobular septa thickening (52cases,86.7%),subpleural curvilinear opacities (52 cases,86.7%),ground-glass opacities (26cases,43.3%),reticular pattern (45 cases,75%),peri-focal emphysema (48cases,80%),bronchiectasis (9cases,15%),honeycomb pattern (19 cases,31.7%).Accompanied emphysema (12 cases),cor pulmonale (9 cases),old pulmonary tuberculosis,pulmonary fungal infection,peripheral lung cancer for one case each were observed.Conclusion:Study of clinical materials in combination with pulmonary changes showed on MSCT and HRCT in SSc patients will be helpful in improving the accuracy of diagnosis and differential diagnosis of this disease. |
