<unk> , a type of pleural effusion is the accumulation of chyle in the pleural cavity secondary to destruction or obstruction of the thoracic duct or its tributaries.  Depending on the etiology,<unk>  could be exudative ( tuberculosis) or transudative (svc obstruction). It is an uncommon but established complication of thoracic surgery.<unk>  is most commonly right-sided (50%) because of the anatomic location of the thoracic duct, left-sided (33.3%), or bilateral (16.66%). Thoracic duct damage above the fifth thoracic vertebra results in a left-sided<unk>  whereas damage to the thoracic duct below fifth thoracic vertebra leads to a right-sided effusion. Some common symptoms of<unk>  include dyspnea, cough, and severe chest pain. Some physical exams finding include decreased breath sounds and dullness to percussion depending on the size and location of fluid. The definitive diagnosis of<unk>  is with thoracentesis and analysis of the pleural fluid showing a reduced concentration of cholesterol <200mg/dl, and an elevated concentration of  triglyceride >110 mg/dl.  Management of<unk>  may be conservative or surgical. Conservative management include total parenteral nutrition, oral low-fat medium-chain triglyceride, and octreotide injections. Surgical management include tube thoracostomy, pleurodesis, pleurectomy, pleuroperitoneal shunt, and thoracic duct ligation.
