硬皮病的胸部高分辨率CT表现

High resolution CT features of scleroderma

目的 探讨硬皮病的胸部HRCT表现及其临床应用价值。方法 对 16例硬皮病病人行HRCT扫描 ,并对其表现进行分析。结果 16例硬皮病病人中 ,11例 ( 68.8% )可见两肺内磨玻璃密度影 ;14例 ( 87.5 % )显示弥漫性或散在、局灶小叶间隔增厚 ;6例 ( 3 7.5 % )出现胸膜下线影 ;9例 ( 5 6.3 % )出现蜂窝影 ,以两肺下野外带常见 ;10例 ( 62 .5 % )可见间隔旁或瘢痕旁肺气肿改变 ;7例 ( 43 .8% )出现纵隔淋巴结增大 ;9例 ( 5 6.3 % )有食管扩张改变。结论 HRCT可以显示硬皮病的细微病变 ,在硬皮病的诊断和治疗中具有重要价值。

Objective To explore the high resolution CT (HRCT) features of scleroderma and its value in clinical application. Methods Sixteen cases of scleroderma were examined with HRCT, and the HRCT features were analyzed. Results Of all 16 cases, ground glass opacities were seen in 11 (68.8%) cases, scattered or local interlobular septal thickening in 14 (87.5%), parallel subpleural lines in 6 (37.5%), honeycombing with a predominance in lower lung peripheral zones in 9 (56.3%), paraseptal and paracicatricial emphysema in 10 (62.5%), enlarged mediastinal lymph nodes in 7 (43.8%), and esophageal dilatation in 9 (56.3%). Conclusion HRCT can show the delicate metastasis of scleroderma, it plays an important role in the diagnosis and treatment of scleroderma.
