title: Symposium on Nonpulmonary Aspects in Chest Radiology. The pulmonary ligament.
abstract: The pulmonary ligament forms an important attachment of the lower lobe to the mediastinum and therefore influences the ultimate configuration of pneumothorax, lower-lobe atelectasis, and mediastinal pleural effusions. Since the ligament consists of a double pleural sheath, under certain circumstances fluid, air, and so on can collect within it, producing a lesion of triangular configuration. The latter must be differentiated from an air cyst or atelectasis.
