A 60-year-old man was admitted to the hospital because of dyspnea on exertion in November 1990. He had a history of asbestos exposure and chest CT scans showed bilateral pleural thickening with calcification and oval-shaped consolidation in the right lower posterior lung field. A chest CT scan obtained in May 1994 showed that the shadow had become smaller and more round. Its size continued to decrease, and in June 1997 the "comet-tail sign" was observed. This is the longest interval between initiating of follow-up and development of round atelectasis yet reported.
一名60岁男性因劳力性呼吸困难于1990年11月入院。他有石棉接触史，胸部CT扫描显示双侧胸膜增厚伴钙化，右下后肺野有椭圆形实变。1994年5月的胸部CT扫描显示阴影变小且更呈圆形。其大小持续减小，1997年6月观察到“彗尾征”。这是迄今报道的从开始随访到圆形肺不张出现的最长间隔时间。
