Pulmonary cystic nodules are a relatively frequent finding in chest computed tomography (CT). There is a possible association between this finding and lung cancer.
To report eight patients with malignant lung cystic lesions.
Retrospective analysis of images in a CT database from 2007 to 2015, looking for cystic lesions of the lung with wall thickening, whose pathological diagnosis was lung cancer.
We identified eight patients with cystic nodules aged 44 to 77 years, of which five were women. Six were active and two former smokers. The pathological diagnosis was adenocarcinoma in seven cases and squamous cell in one. The mean diameter of the cystic lesions was 11.5 mm. The mean diagnostic delay time was 871 days (range 0-1592). The main finding was a gradual thickening of the nodule walls.
The presentation of lung cancer as cystic nodules is uncommon. In this series, the change in morphology due to a thickening of the walls with or without a diameter increase, was the clue for the diagnosis.
肺囊性结节是胸部计算机断层扫描（CT）中较为常见的表现。这一表现与肺癌之间可能存在关联。
报告8例肺恶性囊性病变患者。
回顾性分析2007年至2015年CT数据库中的图像，寻找伴有壁增厚的肺囊性病变，其病理诊断为肺癌。
我们确定了8例年龄在44至77岁之间的囊性结节患者，其中5例为女性。6例为现吸烟者，2例为既往吸烟者。病理诊断7例为腺癌，1例为鳞状细胞癌。囊性病变的平均直径为11.5毫米。平均诊断延迟时间为871天（范围0 - 1592天）。主要表现为结节壁逐渐增厚。
肺癌表现为囊性结节并不常见。在本系列中，壁增厚伴或不伴直径增加导致的形态改变是诊断的线索。
