| 摘要 目的：分析肺类癌的CT影像表现，结合文献复习以提高对该病的认识。方法：回顾性分析7例经病理证实的肺类癌的CT表现，其中3例行胸部CT平扫检查，4例行胸部CT平扫及增强扫描。结果：7例患者中有6例为典型类癌，1例为非典型类癌。6例典型类癌中：1例为微瘤型类癌，表现为右侧肺门旁支气管扩张、结石及条片状影；1例为硬化性血管瘤合并类癌，表现为右侧肺门旁肿块，边缘较光整，伴晕征；2例为右侧肺门旁肿块，边缘光整，明显强化，伴有邻近支气管扩张或支气管粘液嵌塞、远端伴阻塞性肺不张或肺炎改变；2例表现为肺内孤立小结节，边缘光整，无强化。1例非典型类癌表现为不均匀强化的右肺门旁肿块，伴右肺门、纵隔淋巴结转移。结论：肺类癌的CT影像表现多样，典型病例的CT表现具有一定的特征性。 |

| ABSTRACT Objective: To analyze CT manifestations and review related literatures of pulmonary carcinoid tumors. Methods: Seven cases of lung carcinoid tumors, confirmed by pathology, were retrospectively collected and analyzed its CT findings. Of seven cases, three cases underwent chest non-enhanced CT scan, four cases underwent chest non-enhanced and contrast-enhanced CT. Results: For seven cases of pulmonary carcinoid tumors, there are six cases typical carcinoid tumors and one case was atypical carcinoid. For six cases typical carcinoid tumors: one case of carcinoid tumorlet showed bronchiectasis, stones and patchy shadow in the right parahilar region; one case of sclerosing hemangioma concomitant carcinoid showed a mass with distinct margin and halo sign in the right parahilar region; two cases were markedly enhancing right parahilar mass with smooth surface, and also adjacent bronchiectasis or bronchial mucoid impaction, distal obstructive atelectasis or pneumonia can be found; two cases showed non-enhancing small solitary pulmonary nodules with smooth margin. One atypical carcinoid showed heterogeneously enhancing right parahilar mass with lymph node metastasis in the right hilar and mediastinal region. Conclusion: The lung carcinoid tumors can present diverse CT findings and some CT features may be specific for typical carcinoid tumors. |
