目的:研究纵隔型肺癌的影像学表现。方法:回顾性分析17例经手术病理证实的纵隔型肺癌的X线和CT资料。结果:17例中手术证实中央型肺癌6例,周围型肺癌9例,隐匿型肺癌2例。病理类型鳞癌7例,腺癌4例,小细胞癌6例。17例均有呼吸道症状。单侧,外缘分叶、毛刺,与纵隔锐角相交,内缘脂肪线影,支气管以及肺内继发性改变,淋巴结肿大以中纵隔和肺门多见,是纵隔型肺癌多见的影像表现。结论:纵隔型肺癌有一定的特点,CT在鉴别中更有价值。
Objective: To study the imaging findings of mediastinal lung cancer. Methods: A retrospective analysis of 17 cases of pathologically confirmed mediastinal lung cancer by X-ray and CT data. Results: Among the 17 cases, 6 cases of central lung cancer, 9 cases of peripheral lung cancer and 2 cases of occult lung cancer were confirmed by operation. Pathological type squamous cell carcinoma in 7 cases, adenocarcinoma in 4 cases, 6 cases of small cell carcinoma. All 17 patients had respiratory symptoms. Unilateral, the outer edge of leaves, burr, and the acute angle of mediastinal cross, the edge of fat line shadow, bronchial and pulmonary secondary changes, lymph nodes in the mediastinum and hilar more common mediastinal lung cancer is more common image performance . Conclusion: Mediastinal lung cancer has some characteristics, CT is more valuable in the identification.
