It is suggested that the ratio of the area of the mediastinal computed tomographic image to that of the lung computed tomographic image can be a prognostic factor in patients with small peripheral lung adenocarcinoma.

Our results suggest that the computed tomographic image of small lung adenocarcinoma is correlated with biologic activities and thus provides possible prognostic information.

Relapsing Polychondritis is a rare disease which causes the repetitive inflammation of cartilage and connective tissues. Although the large airway is sometimes involved and the stenosis of them often influences the prognosis of the patients, there have been few reports concerning the manifestation of the peripheral lung. A 60-year-old man with pulmonary fibrosis was admitted to a regional hospital due to sudden deafness, and then he suffered from relapsing polychondritis. During the steroid therapy, he also suffered from bilateral pneumothoraces. His computed tomogram revealed many bilateral bullae, emphysematous changes, and fibrotic changes in bilateral lungs. The mechanism of generating peripheral pulmonary manifestations is also discussed.
