The symptoms of a<unk>  depend its size and the underlying cause. A small<unk>  may not cause any symptoms and only be detected on a chest X-ray performed for another reason. A large<unk>  may lead to breathlessness or a feeling of pressure in the chest, caused by fluid restricting the expansion of the lungs, although large<unk> es may remain asymptomatic if the<unk>  has accumulated slowly, as the lungs may have had time to become used to the pressure. Fever or chest pain are not usually associated with<unk> , as chyle does not generate inflammation by itself. On examination,<unk>  may lead to reduced breath sounds on the affected side, associated with a dull sound when the chest is tapped or percussed. In cases of postoperative<unk> , the first sign may be persistent drainage from intercostal drains. Large<unk> es may cause signs related to the loss of nutrients, including features of malnutrition or decreased ability to fight infections. Rapidly accumulating<unk> es can cause a sudden drop in blood volume, leading to low blood pressure.
