摘　　要：目的 探讨肺炎型肺癌的CT表现,提高诊断水平,减少误诊.方法 回顾性分析经病理证实的24例肺炎型肺癌的临床及CT资料,观察病灶分布、是否伴有不规则小结节、实变区内有无支气管充气征、不规则小囊腔及病灶周边有无磨玻璃影环绕等.结果 两肺多发分布6例;单发分布18例：上叶5例,中叶3例,下叶10例.所有病灶均为外周分布,伴有小结节11例,实变区内支气管充气征14例,不规则小囊腔7例,周边有磨玻璃影环绕13例.24例中首诊为肺炎23例,肺结核1例.结论 肺炎型肺癌CT表现具有一定特点.对积极抗感染治疗吸收不佳的＂肺炎＂应警惕肺炎型肺癌的可能,需尽早行活检确诊.Objective To discuss the imaging features of the pneumonic-type lung carcinoma （PTLC） in order to improve the diagnosis and reduce the misdiagnosis. Methods The clinical and CT data in 24 patients with PTLC proved by pathology were retrospectively reviewed and analyzed in the study, including the manifestation and distribution of consolidation, accompanying irregular nodules, the presence of air bronchogram, ground glass opacity, and cysts or cavities within the consolidation. Results Multi-lobe consolidations appeared in 6 cases, and single lobe consolidation in 18 cases including upper lobe in 5, middle lobe in 3 and lower lobe in 10. All lesions were in peripheral distribution with surrounding irregular nodule in 11, air bronchogram sign within consolidation in 14, cysts or cavities in 7, and peripheral ground-glass opacity in 13. In all patients, 23 were first diagnosed as pneumonia and 1 as pulmonary tuberculosis. Conclusion PTLC has some characteristic CT features. Poor effect of pneumonia after antibiotic therapy may suggest a possibility of PTLC, and the biopsy is necessary as soon as possible.
