Enhancement of collapsed lung: a potential pitfall in CT interpretation.
In the presence of a pleural effusion there may be compression of adjacent lung causing segmental atelectasis. In some effusions minor degrees of atelectasis give rise to a fine rim of enhancing lung on computerized tomographic (CT) examination which should not be misinterpreted as extravasated contrast from aortic or oesophageal lumen.
