中心气道原发肿瘤的CT影像表现

目的：探讨中心气道原发肿瘤的CT表现,提高该病的CT诊断水平。方法：回顾性分析经病理证实的189例中心气道原发肿瘤患者的基本临床资料及CT表现。分析内容包括：患者的性别、年龄,肿瘤的生长部位、大小、形态、边缘、密度、强化程度、纵隔淋巴结及肺内情况。结果：男138例,女51例;患者年龄3～84岁（平均年龄56.3岁±17.7岁）;恶性肿瘤165例、良性24例;肿块直径3～67mm,平均（25±18.6）mm;肿块位于气管73例,隆突8例,左主支气管37例,右主支气管28例,中间段支气管12例;肿块表现为管内型35例,管壁型29例,管外型6例,混合型88例;病变表面光滑40例,不光滑118例,宽基底138例,窄基底20例;37例肿瘤内有坏死,3例瘤内有钙化;47例纵隔及肺门淋巴结肿大,12例合并肺内转移,8例合并胸腔积液,75例合并肺不张及阻塞性肺炎。结论：不同类型的中心气道肿瘤在CT影像表现上具有一定特点。

CT Imaging Characterization of Central Airway Primary Tumors

Objective： To study the CT characterize of central airway tumors, improve the CT diagnosis of the disease. Methods： Review of basic clinical data and CT findings of 189 cases of the central airway pathological confirmed primary tumor patients, Analyses include： sex, age, growth site, tumor size, shape, density, edge, degree of enhancement, mediastinal lymph node and lung conditions. Results： male： 138, female： 51; age among 3 to 84（average age 56.3 ± 17.7）, 165 cases is malignant, 24 is benign. The tumor diameter 3-67 mm, average（25 ± 18.6） mm. Mass in 73 cases of trachea, and 8 cases in carina, left main bronchus in 37 cases, right main bronchus in 28 cases, 12 cases of middle bronchus. The mass was found intracanalicular type in 35 cases, walltype in 29 cases, extraluminal in 6 cases, 88 cases of mixed type. lesion in 40 cases of smooth surface, non smooth in 118 cases, 138 cases of wide basal, narrow base in 20 cases. 37 cases of tumor necrosis, 3 cases of tumor with calcification; 47 cases of mediastinal and hilar lymph nodes, 12 cases with lung metastasis, 8 cases with pleural effusion, 75 cases with pulmonary atelectasis and obstructive pneumo. Conclusion： Different types of central airway tumors have certain features in CT images.
