ABSTRACT
Chylothorax is a rare cause of pleural effusion, secondary to accumulation of lymph in the pleural space. Diagnosis is based on the triglyceride and cholesterol content of pleural fluid obtained with thoracentesis. Chylothorax is usually described as traumatic or nontraumatic. Causes of nontraumatic chylothorax include a wide range of differential diagnoses. Thoracic malignancies and lymphoma are the most common causes and are responsible for chylothorax by extrinsic compression or invasion of the thoracic duct. One of the causes of nontraumatic chylothorax is lung cancer. The main cause of chylothorax is traumatic, typically postsurgical, secondary to iatrogenic direct puncture of the thoracic duct during thoracic surgery. Chylothorax is associated with significant morbidity and mortality if left untreated. The etiology, clinical presentation, and diagnosis and the management of chylothorax must be well understood to diagnose and provide appropriate therapy to patients.
