Chylothorax is defined as accumulation of which fluid in the pleural space?

• A. Lymphatic fluid
• B. Blood
• C. Pus
• D. Serous transudate

Answer: (A)

Chylothorax is the accumulation of lymphatic fluid (chyle) in the pleural space. This fluid comes from the lymphatic system and is rich in fat absorbed from the gut, containing chylomicrons that give it a milky appearance. It leakage typically results from injury or obstruction of the thoracic duct or other thoracic lymphatic channels, allowing chyle to accumulate in the pleural cavity. This distinguishes it from blood (hemothorax), pus (empyema), or serous transudate, which have different origins and compositions.
