title: Rounded atelectasis of the lung: A pictorial review.
abstract: Rounded atelectasis of the lung is well described in medical literature, but still difficult to diagnose. Since lesions give no clinical symptoms in patients, radiologists are often the first to recognize the round lesion in an X-ray picture or a CT scan. Rounded atelectasis is an atypical form of lung collapse that usually occurs adjacent to scarred pleura and can be mistaken for lung cancer. Patients with rounded atelectasis have a history of asbestos exposure or pleural effusion due to various causes. When characteristic imaging findings are present, the diagnosis is rarely dubious and no further investigation is necessary. However, differential diagnosis of rounded atelectasis poses a challenge to pulmonary specialists and radiologists.
