| 目的 比较中央气道内腺样囊性癌（ACC）与黏液表皮样癌（MEC）的临床及CT特征。方法 回顾性分析接受胸部CT检查并经手术或支气管镜病理证实的76例中央气道涎腺肿瘤患者，其中ACC 45例、MEC 31例。所有患者术前均接受胸部CT平扫，其中38例ACC、29例MEC加行CT增强扫描，比较ACC与MEC的生长部位、最大径、生长方式、强化程度及阻塞性炎症、阻塞性肺不张、淋巴结增大及胸腔积液等CT表现差异。结果 MEC患者年龄低于ACC患者（P<0.01），两者咳嗽、咳痰、发热、咯血、呼吸困难、胸痛发生率差异均无统计学意义（P均>0.05）。与MEC比较，ACC易发生于气管、多呈浸润性生长、强化程度较小、阻塞性炎症发生率较低（P均<0.05），而肿瘤最大径及阻塞性肺不张、淋巴结肿大、胸腔积液征象发生率两者差异均无统计学意义（P均>0.05）。结论 中央气道涎腺肿瘤发病年龄较轻。ACC好发于气管，多呈浸润性生长，增强CT呈轻-中度强化；MEC好发于叶、段支气管，多呈膨胀性生长，增强CT明显强化。MEC阻塞性炎症发生率高于ACC。 |

| Objective To compare CT features and clinical manifestations of adenoid cystic carcinoma (ACC) and mucoepidermoid carcinoma (MEC) in the central airway. Methods A total of 76 patients with central airway salivary gland tumor proved by surgery or biopsy (45 patients with ACC and 31 patients with MEC) were analyzed retrospectively. All patients underwent chest CT, among them 38 patients with ACC and 29 patients with MEC underwent contrast enhanced CT. CT features of the tumor, including growth location, maximum diameter, growth pattern, enhancement, obstructive pneumonia, atelectasis, lymphadenopathy and pleural effusion were evaluated. Results Patients with MEC were younger than those with ACC (P<0.01). There was no significant difference in incidence rate of cough, expectoration, fever, hemoptysis, difficulty breathing nor chest pain between two groups (all P >0.05). Compared with MEC, ACC was more likely to occur in trachea, behaved as infiltrative growth, less enhancement and lower incidence of obstructive inflammation(all P<0.05). However, there was no significant difference in tumor maximum diameter and the incidence of obstructive atelectasis, lymph node enlargement nor pleural effusion between MEC and ACC patients (all P>0.05). Conclusion The age of onset of central airway salivary gland tumor is younger. ACC is more likely to occur in the trachea, most of them show invasive growth, while enhancement CT shows mild to moderate enhancement. MEC is more likely to occur in lobar and segmental bronchi, most of them show expansive growth and significantly enhancement on CT. The incidence of obstructive inflammation is higher in MEC patients than in ACC patients. |
