👉 Chylothorax is a condition in which the left side of the chest, or "chylus", becomes larger than usual. This can occur when the right heart muscle fails to pump enough blood through the trachea (windpipe), causing fluid pressure to build up and cause swelling in the lungs. The term comes from Greek mythology, where Chylothorax is a type of chest infection that leads to swollen lymph nodes on the left side of the chest.
