Liver cyst refers to water-filled sacs which build up in liver. Most liver cysts are benign which means they are not cancerous. Usually, people with liver cysts don’t require medical treatment, unless liver cysts cause serious symptoms or affect liver functions. This article will talk about what causes liver cyst and whether they can go away on their own.
What causes liver cyst?
Liver cysts are the result of a malformation in the bile ducts, although the exact cause of this malformation is unknown. Bile is a fluid made by the liver, which aids in digestion. This fluid travels from the liver to the gallbladder through ducts or tube-like structures.
Cysts that grow in the liver are often congenital. This term means that the cysts formed before birth, while a person was developing in the womb.
Infection with an Echinococcus tapeworm can also lead to liver cysts. These parasites are often present in farm animals or animals that live on farms, which can include dogs, wolves, and coyotes. A person can become infected with Echinococcus through exposure to the feces of these animals.
The symptoms associated with liver cysts include upper abdominal fullness, discomfort, or pain. A small number of patients bleed into the cyst, which causes sudden and severe right upper quadrant and shoulder pain. The bleeding stops on its own, and the pain then improves over the next several days. However, in many cases, people live with liver cysts without knowing them. Thereby, you are suggested to take medical test each year.
