Linea paratrachealis dextra
Linea paratrachealis dextra
定义
右气管旁条纹由气管壁、纵隔结缔组织及气管旁胸膜构成。气管内的气体与充气的右肺上叶共同勾勒出两者之间软组织的轮廓。
正常影像学表现：
右气管旁条纹起自锁骨水平，向下延伸，投影穿过上腔静脉，止于奇静脉弓水平的右气管支气管角。该条纹正常最大厚度为4毫米，且宽度应均匀一致。
据报道，右气管旁条纹可在83%至97%的后前位胸部X线平片上显示。
异常影像学表现：
该条纹轮廓异常、增宽或消失，可能由其任一组成部分的病变所致，范围涵盖气管黏膜至胸膜腔，包括气管癌、气管旁肿块（最常见为淋巴结肿大）以及胸腔积液或胸膜增厚。
