Abstract Objective: To analyzed the CT features of a group of lung cancer cases occurred in the honeycomb lung background, to draw attention to interstitial pulmonary fibrosis combined with lung cancer and to improve the diagnosis ability. Methods: Cases of honeycomb lung combined with lung cancer from November 2011 to July 2016 in our hospital were retrospectively collected. All the cases underwent CT(Somatom Definition Flash and Omatom Definition AS) scanning on supine position, with 5 mm slice thickness and 1 mm reconstruction. Size, location, morphological features and dynamic CT characteristics of the lesions were reviewed using unified image window. Results: There were 36 patients diagnosed of interstitial pulmonary fibrosis with lung cancer by pathology. Twenty-six(72.2.0%) lesions were lobulated with blurred edge. Four cases(11.1%) showed irregular consolidation. Two cases(5.6%) showed irregular fibers. Four cases(11.1%) showed a small triangle or wedge consolidation under the pleural in the first CT examination. Conclusion: Images should be carefully analyzed in the chest CT of the patients with a honeycomb lung, especially the nodules and patches of consolidation, which should be followed up.
