Objective to investigate the radiological features of pulmonary mucinous carcinoma on HRCT (High-resolution Computed Tomography). Materials and methods: The HRCT features of the 60 cases of pulmonary mucinous carcinoma confirmed by pathology were analyzed, while the clinical data of them also were reviewed retrospectively in our hospital during January 2013 and December 2018. Results: Our cohort included 39 women and 21 men, age ranged from 34 to 85 years old (mean 63.3 years old). The 60 patients were classified into 2 patterns at HRCT: node/mass (n=45), consolidation (n=15). Of the 60 cases, 34 (56.7%, 34/60) patients presented sign of air-like lucency (bubble-like lucency, air bronchogram or cavitation), 27 (45%, 27/60) patients present the sign of vessel convergence on HRCT. For the 45 cases node/mass lesions, 23 (51.1%, 23/45) lesions appeared airlike lucency, 30 cases show lobulations (67%, 30/45) and 28 (62.2%, 28/45) cases show speculations. Statistics shows that there were no relationships between sign of air-like lucency and sign of vessel convergence, speculation as well as lobulation were P=0.2012, P=0.2875 and P=0.1337, respectively. Conclusion: On HRCT, a pulmonary mucinous carcinoma might appear sign of air-like or vessel convergence, while signs of lobulation and speculation might appear in lesions showed as nodule/mass pattern. Sign of air-like lucency was independent from signs of vessel convergence, lobulation and speculation.
