a pleural effusion consisting of chyle or a chylelike fluid; it may be either congenital (such as in babies) or acquired from trauma or disease states. There are two types: chylous effusion, due to leakage of chyle from the thoracic duct, and chyliform or pseudochylous effusion, consisting of chylelike fluid, the result of a chronic disease such as tuberculosis.
An accumulation of chylous fluid in the pleural space.
chylothorax/chy·lo·tho·rax/ (-thor´aks) pleural effusion of chyle or chylelike fluid.
Etymology: Gk, chylos + thorax, chest
a condition marked by the effusion of chyle from the thoracic duct into the pleural space. The cause is usually a traumatic injury to the neck or a tumor that invades the thoracic duct. Treatment is directed at repairing damage to the duct.
chylothoraxAn uncommon and potentially life-threatening condition due to disruption of the flow of lymph into the thoracic duct, which is caused by penetrating or blunt trauma to the neck, chest or upper abdomen, or surgery involving the oesophagus, lung, pleura, mediastinum and heart, as well as other conditions (e.g., lymphangioleiomyomatosis or lymphoma).
Pleural effusion and nutritional deterioration due to major loss of electrolytes, proteins, lipids and vitamins, often accompanied by immune deficiency and lymphopenia.
An accumulation of milky chylous fluid in the pleural space, usually on the left.
chylothoraxA rare condition of accumulation of CHYLE in the space between the lung coverings (pleural cavity). The chyle escapes from the thoracic duct, usually as a result of injury.
the presence of effused chyle in the pleural cavity. Occurs most commonly in dogs and cats, caused by traumatic injury to the thoracic duct, neoplasms in the cranial mediastinum, or a congenital abnormality of the duct.
