Clinical Information for Pleural effusion, not elsewhere classified (J90)

Pleural Effusion - Presence of fluid in the pleural cavity resulting from excessive transudation or exudation from the pleural surfaces. It is a sign of disease and not a diagnosis in itself.

Pleural Effusion, Malignant - Presence of fluid in the PLEURAL CAVITY as a complication of malignant disease. Malignant pleural effusions often contain actual malignant cells.

Hydrothorax - A collection of watery fluid in the pleural cavity. (Dorland, 27th ed)

Pleural Cavity - Paired but separate cavity within the THORACIC CAVITY. It consists of the space between the parietal and visceral PLEURA and normally contains a capillary layer of serous fluid that lubricates the pleural surfaces.
