Background. A number of different diseases are characterized by airspace consolidation in the lungs. The early diagnosis and treatment in cases of lung cancer with airspace consolidation can thus be challenging. Case. A 74-year-old man with prostate cancer underwent thoracoabdominal computed tomography (CT) as part of an examination prior to treatment, which revealed ground-glass opacity in the basal segment of the right lower lobe. Follow-up CT performed one year later further showed extended ground-glass opacity and irregular airspace consolidation, and bronchoscopy did not lead to a definitive diagnosis. Another follow-up CT performed one year later showed that the ground-glass opacity had extended to the entire right lower lobe and that airspace consolidation had extended primarily from the basal segment of the right lower lobe. In addition, the volume of the right lower lobe had decreased. These findings were specific to the right lobe, and none of the other lung lobes were affected. Thoracoscopic right lower lobectomy was performed for the diagnosis and treatment of airspace consolidation that had slowly expanded in the right lower lobe. On pathology, the region characterized by airspace consolidation was diagnosed as lepidic-predominant alveolar cell adenocarcinoma (pT4N0M0, p-stage IIIA). Conclusion. Findings of airspace consolidation with slow expansion indicate the presence of neoplastic disease, which requires a careful diagnosis and treatment.
