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.
胸腔积液存在时，可能会压迫相邻肺组织，导致节段性肺不张。在一些胸腔积液中，轻微程度的肺不张在计算机断层扫描（CT）检查时会产生一圈强化的肺组织边缘，不应将其误解为来自主动脉或食管腔的造影剂外渗。
