A malignancy must be considered whenever a mass lesion is encountered on a chest roentgenogram. Unless an unequivocal diagnosis of a benign lesion is made, thoracotomy is usually indicated. Rounded atelectasis, while only having been recently described, is being encountered with increasing frequency. As illustrated by our three cases, radiologic diagnosis of this entity is a major criterion for judging the benignity of a mass and obviates the need for a thoracotomy.
每当胸部X线片上发现块状病变时，都必须考虑恶性肿瘤的可能。除非能明确诊断为良性病变，否则通常需要进行开胸手术。圆形肺不张虽然是最近才被描述的，但发现的频率越来越高。正如我们的三个病例所示，对该实体的放射学诊断是判断肿块良性的主要标准，可避免进行开胸手术。
