呼吸肺肿瘤的影像诊断ppt课件

Thanks for your attendance欢迎光临指导,影像学教研室 江勋源,临床医技课之 呼吸系统的放射诊断 肺肿瘤的影像诊断Imaging Diagnosis of Lung Tumor,In todays lesson, we are going to study,Classifications of lung tumor 肺肿瘤的分类Imaging appearance of central lung cancer 中心型肺癌的影像表现Imaging appearance of peripheral lung cancer周围型肺癌的影像表现Special appearances of lung cancer 肺癌的特殊表现Imaging of metastatic lung cancer 肺转移瘤的影像表现,Classification肺肿瘤的分类,According to its origin, lung tumor can be classified as 根据肺肿瘤的起源分为：(一)Primary原发性 1 . Benign : rare 良性 少见 2. Malignant : 恶性 A. 98% are Primary lung cancer 恶性中98%是原发性支气管肺癌,简称肺癌 B. Sarcoma 98% are Primary lung cancer 恶性中98%是原发性支气管肺癌,简称肺癌 B. Sarcoma 2% 少数肺肉瘤(二)Secondary : Metastatic lung cancer or lung metastasis 继发性: 转移性肺癌(肺转移癌),1. Central 中心型 （中央型）： 段支气管开口以上 2. Peripheral外围型 （周围型）： 肺段以下 3. Diffuse （弥漫型） Bronchioloalveolar Carcinoma 细支气管肺泡癌 BAC,二.pathological classification (gross) 大体病理类型: 按其发生部位分为：,二.Imaging appearances of Central Lung Cancer 中央型肺癌的影像表现,Direct signs: tumor mass, Bronchial obstruction 直接征象：肺门肿块,支气管阻塞 2. Indirect signs: signs of obstructive complications 间接征象： 即支气管阻塞所致肺部征象 A. Obstructive emphysema 阻塞性肺气肿 B . Obstructive pneumonia 阻塞性肺炎 C. Obstructive atelectasis 阻塞性肺不张,Review II,Primary lung cancer 1. 中央型： 2.周围型：肺内肿块影为主. 分叶,毛刺,空洞 Peripheral: Well-defined mass with lobular,spicular edge and cavity 3.两种特殊类型,Primary lung cancer,1. 中央型 2.周围型： 3.特殊类型：肺尖癌与 细支气管肺泡癌： special types of lung cancer: Pancoasts tumor and bronchioloalveolar cancinoma BAC: diffuse nodules or masses on both lung肺泡癌：两肺广泛弥漫结节或肿块样病灶转移性肺肿瘤 两肺广泛弥漫结节或肿块样病灶diffuse nodules or masses on both lung,原发性纵隔肿瘤Primary mediastinal tumors,前纵隔：甲状腺，胸腺瘤，畸胎瘤Anterior：Goiter, thymoma, teratoma中纵隔：淋巴瘤，支气管囊肿Middle ：Lymphoma, Bronchical cyst 后纵隔：神经源性肿瘤Posterior：Neurogenic tumors,上纵隔甲状腺： Goiter,前上纵隔畸胎瘤：Teratoma,前上纵隔胸腺瘤：Thymoma,前纵隔胸腺瘤：Thymoma,中纵隔支气管囊肿Middle:Bronchnic Cyst,后纵隔神经源性肿瘤Posterior:Neurogenic tumor,同学们辛苦了，今天晚上我请客！Thanks for your attendance, The dinner is on me!I hope youll enjoy it!,Thank you,偶对好山留客坐，绿阴庭屋日将西,偶对好山留客坐，绿阴庭屋日将西
