Hepatic cystic hamartoma

Hepatic cystic hamartoma, also sometimes called mesenchymal hamartoma of the liver or biliary hamartoma (von Meyenburg complex), is a rare, non-cancerous growth that forms in the liver. It develops when normal liver tissue grows in an unusual, disorganized way, creating one or more fluid-filled sacs (cysts) mixed with fibrous tissue. These growths are benign, meaning they are not cancer, but they can still cause problems depending on their size and location in the liver. Many people with hepatic cystic hamartoma have no symptoms at all, and the condition is often found by accident during an ultrasound or scan done for another reason. When symptoms do occur, they may include abdominal discomfort, a feeling of fullness or pressure in the upper right belly, or a noticeable lump. In rare cases, large growths can press on nearby organs or bile ducts, causing more serious problems. Treatment depends on the size of the hamartoma and whether it is causing symptoms. Small, asymptomatic cases are often just monitored with regular imaging. Larger or symptomatic cases may require surgical removal. The overall outlook for most people is very good, especially when the condition is caught early and managed appropriately.
