Lung cancer associated with cystic airspacesis a distinct subtype of lung cancer with unique imaging and pathological features. Lung cancer screening can identify patients with cystic lesions on imaging, but distinguishing benign from malignant lesions remains challenging. The pathologic types of LCCAs vary, and early diagnosis and accurate identification are of great clinical value for patient management and improved prognosis. Clinicians should pay more attention to LCCAs to promote early diagnosis, improve the timing of interventions, and achieve better survival benefits for patients.  \nKeywords  \nlung cancer, CT imaging, pathology, diagnosis, treatment  \nReceived: 27 January 2026; Revised: 31 March 2026; Accepted: 21 April 2026  \n1. Introduction  \nLung cancer is one of the malignant tumors with the highest morbidity and mortality rates worldwide. 1 The latest data show that the incidence of lung cancer is gradually increasing, and the mortality rate of lung cancer has exceeded that of breast cancer, making lung cancer the leading cause of death from tumor-related diseases.2,3 Lung cancer is a significant problem affecting public health, imposing a heavy burden on the government healthcare system and the socio-economy. In the past decade or so, with the development and widespread use of low-doseCT, many extensive cohort studies have determined that low-dose CT screening can increase the diagnosis and treatment of lung cancer in its early stages, thereby reducing lung  \n1Department of Pulmonary and Critical Care Medicine, The 1st Affiliated Hospital, Jiangxi Medical College, Nanchang University, Nanchang, Jiangxi, P.
