Case Reports[A case of idiopathic interstitial pneumonia with pneumothorax and pneumomediastinum, accompanied by rapid progression of cystic changes on CT].
A case of idiopathic interstitial pneumonia (IIP) with pneumothorax and pneumomediastinum was presented. A 52-year-old male was admitted with the complaint of cough, fever and dyspnea. Chest roentgenogram revealed bilateral reticulonodular shadow and right pneumothorax. ⋯ The mechanisms of pneumothorax and pneumomediastinum were speculated to be due to the rupture of those cystic lesions which had grown rapidly on follow-up CTs. It was suggested that the formation of honeycombing occurred within a few months and the increasing of honeycombing might be accompanied by so-called acute exacerbation of IIP. We propose that follow-up CTs were useful for the chronological study for interstitial lesions of IIP.
