This pictorial review of fluid containing thoracic lesions provides a framework for assessment of the various imaging features and directs integration of observations into a specific diagnosis. Sample cases will illustrate typical and atypical entities. Appropriate pitfalls and complications will be discusses.

  Fluid containing thoracic lesions is a diverse group of pathologic conditions. Similar appearing lesions can represent vastly different pathophysiologic processes. This exhibit is highlighting a systematic approach and concepts helpful to formulate focused differential diagnosis and guide proper management. The lesions are organized in the following groups: Location relative to the chest wall, diaphragm, pleura and pericardium; distribution in the lung zones; position in mediastinum; presence of air-fluid or fluid-fluid levels; presence and appearance of a solid component; occurrence of loculation or septations; distribution of fluid within the lesion; lesion size; fluid characteristics pertinent to the modality (CT density, MRI signal intensity, US echogenicity); appearance of the lesion wall; characteristics of blood flow in the lesion; reactive changes on the neighboring tissues; presence of underlying or predisposing lung disease.
