👉 Pyohemothorax is a condition that describes an enlarged spleen. It occurs when there are too many cells in the spleen, which can lead to inflammation and pain. The spleen is a large organ in the digestive system responsible for producing white blood cells, which fight off infections. The spleen also plays a role in regulating blood volume, as it helps to distribute red blood cells throughout the body. In most cases of pyohemothorax, there's no need for treatment
