What is the cause of multiple low-density nodules in the liver?

There are multiple low-density nodules in the liver. This situation may be caused by two reasons. One is hemangioma and the other is liver cyst. Liver cyst is a benign lesion. If there are no special circumstances, it generally does not require treatment. Another situation is liver cancer. At this time, further diagnosis is needed. There are many causes of liver cysts, such as congenital cysts, etc.

1. What is the cause of cysts on the liver? Liver cysts are a relatively common benign liver disease. It can be divided into parasitic and non-parasitic liver cysts. The former is most common with hepatic echinococcosis; the latter can be divided into congenital, traumatic, inflammatory and tumorous liver cysts, among which congenital liver cysts are the most common. The liver cysts usually referred to are congenital liver cysts. 1. Retention liver cyst is caused by increased secretion of a bile duct in the liver due to inflammation, edema, scar or stone obstruction, or bile retention. Most of them are single, but they may also be in the late stage due to blunt contusion of the liver, leading to central rupture. The lesion cyst is filled with blood or bile, and the capsule is fibrous tissue. It is a single pseudocyst.

What are the dangers of having cysts on the liver? Liver cysts are a common benign liver disease and can be divided into parasitic, non-parasitic and congenital hereditary. The cause of liver cysts is mostly due to developmental disorders of small intrahepatic bile ducts, and single liver cysts are caused by ectopic bile ducts. Liver cysts grow slowly, so they may be asymptomatic for a long time or for life. Their clinical manifestations vary with the location, size, number of the cysts, whether they compress adjacent organs, and whether there are complications. In addition, liver cysts are actually benign masses that often appear in other organs. Most patients do not have any obvious symptoms. Generally speaking, people without obvious symptoms or with normal liver function do not need treatment. But if the symptoms are intolerable or have affected liver function, the consequences can be serious. Experts warn that about 50% of patients with liver cysts have polycystic kidney disease, which may cause symptoms such as hypertension, hematuria, pain in the renal area, and renal insufficiency. The hazards of liver cysts when they are complicated by cyst infection, bleeding, rupture, or torsion may manifest as sudden severe abdominal pain, high fever, or symptoms and signs of peritonitis. At the same time, liver cysts can cause pain in the liver area and abdominal distension. Sometimes the cyst suddenly increases in size or becomes infected, which can cause sudden worsening of abdominal pain or fever. Sometimes a mass can be felt in the upper abdomen, and some patients experience abdominal pain, vomiting, and jaundice.
