Abstract Objective: the imaging findings of alveolar carcinoma varied, misdiagnosed, in order to improve the understanding of its imaging features. Methods: to collect a number of hospitals from 2004 to 2016 54 cases of pathologically confirmed 36 cases of pulmonary carcinoma, had chest X-ray two times, CT1 2 times, 3 and 15 cases of bronchial angiography cases of bronchial endoscopy. Results: the first chest X-ray misdiagnosis in 36 cases, 12 cases of misdiagnosis. CT by chest X-ray and CT joint analysis considering 28 cases of bronchial alveolar cell carcinoma. According to the imaging findings were divided into five types: 1, miliary nodules; 2, 3; multiple nodular type; 4, mass; 5, pneumonia Among them, the misdiagnosis rate of pneumonia is the highest. Conclusion: each type of bronchial alveolar carcinoma has its own characteristics. It is expected to improve the correct diagnostic rate and reduce the misdiagnosis rate in time.

细支气管肺泡癌(简称肺泡癌)是发生在肺外周远端细支气管或肺泡的原发性肺癌,其影像表现多种多样,不具特征性,易误诊。为提高对其影像征象的认识,结合临床特点,本人经过多院、多年手术及病理证实54例进行分析,提高本病的临床诊断符合率。
1.材料与方法
54例中男性36例,女性18例,年龄38——82岁,平均年龄51.5岁,发病高峰47——56岁,占55.2%,病病程2月——3年。临床表现:低热14例,咳嗽42例,痰中带血36例,胸痛32例,胸水8例,咳泡沫痰45例,疲乏、消瘦11例,颈部转移瘤压迫上腔静脉出现霍纳氏综合征2例,其中肺结核史4例,糖尿病2例,无自觉症状,体检时发现胸部异常5例。
证实诊断方法:手术+病理组织学54例,经皮肺穿刺活检10例,淋巴结活检8例,纤维支气管镜检15例,痰细胞学检查54例2——4次不等。
54例均摄胸片、CT 检查及病理检查,支气管造影3例,15例支气管镜检查。
2.结果
均以首次胸片为X先诊断统计依据:肺泡癌14或肺癌21共35例占64%,其余分别误诊为:肺炎19例,炎性假瘤2例,肺结核10例,支气管扩张4例,肺霉菌病2例,共38例,占68%,2——4周复查胸片及CT片后纠正诊断16例,占29%。
综合胸片、CT、纤维支气管镜、碘油支气管造影、经皮胸穿刺活检、手术所见,有如下表现:
2.1 病灶部位:双肺广泛性病灶32例,单侧多发性病灶8例,其中右肺27例、左/13例,单发病灶14例,其中右肺8例,左肺,6例,本组资料表明右肺多余左肺,多病灶多余单病。
2.2 病灶形态:按分部、数量、大小情况分为下列几种:
A、肺炎型19例,呈小片状影6例,大片状影13例……
