What Are the Primary Causes of Lesions on the Liver? Non-cancerous blood-filled masses known as hemangiomas are the primary cause of lesions on the liver, according to the California Pacific Medical Center. Other benign causes of hepatic lesions include simple liver cysts, focal nodular hyperplasia, and hepatic adenomas, explains Johns Hopkins Medicine.

Picture of the Liver 1 Hepatitis: Inflammation of the liver, usually caused by viruses like hepatitis A, B, and C. Hepatitis can have non-infectious causes too, including heavy drinking, drugs, allergic reactions, or obesity. 2  Cirrhosis: Long-term damage to the liver from any cause can lead to permanent scarring, called cirrhosis.

MayoClinic Health Library It may be unsettling to know you have a mass in your liver, even if it's a benign mass. There's no evidence that an untreated liver hemangioma can lead to liver cancer. A liver hemangioma is a noncancerous (benign) mass that can occur in the liver. A liver hemangioma is made up of a tangle of blood vessels. Liver hemangioma is sometimes called hepatic hemangioma or cavernous hemangioma. Most cases of liver hemangioma are discovered during a test or procedure for some other condition.

Overview These combined health problems appear to promote the deposit of fat in the liver. For some people, this excess fat acts as a toxin to liver cells, causing liver inflammation and nonalcoholic steatohepatitis, which may lead to a buildup of scar tissue (fibrosis) in the liver.

Understanding Liver Lesions Sarcoidosis is another condition but it isn’t fully understood what causes it. There are a variety of symptoms that can be present when someone suffers from liver lesions. It can be very painful due to the fact that the liver can become inflamed. As it swells up it can cause pressure because it is pushing up against other aspects of the body internally.

- Hepatitis C is caused by virus that affects the liver. Millions of virus attack liver to cause inflammation (hepatitis) and finally scarring (cirrhosis) and in some patients even cancer. The United States has more than twice number of Hepatitis C patients than the HIV.

- “Lesion” is a general word for a tissue abnormality. Liver lesion is a term doctors use for abnormal areas noted on an imaging test of the liver. Most often, liver lesions are seen on an ultrasound, computed tomogram (CT) scan, or magnetic resonance imaging (MRI) scan. The term “liver lesion” is a general term. Liver lesions could be anything from harmless cysts in the liver, to areas of cancer spreading from the colon or breast. The appearance of the lesions on imaging, as well as other diagnoses and test results, can often help explain the cause of liver lesions.

- Infection. Parasites and viruses can infect the liver, causing inflammation and that reduces liver function. The viruses that cause liver damage can be spread through blood or semen, contaminated food or water, or close contact with a person who is infected.

Metastatic Liver Lesions Diagnosis and Treatment When cancer has spread to the liver, it typically does not cause any symptoms. As a result, most patients do not notice any change in their health. Blood tests and imaging, such as CT scan or ultrasound, are important tools to detect metastatic liver lesions at an early stage, when they are most effectively treated.FA may be used for patients who have unresectable metastatic liver lesions, or are too ill to undergo surgical resection, and may be used in combination with other forms of treatment. Surgical resection involves removing a portion of the liver that contains the metastatic lesion.

Non-Cancerous Liver Lesions Diagnosis and Treatment Presently, disease processes within the bile duct that cause bile flow obstruction are the most common cause of pyogenic abscesses. Other causes include intra-abdominal infections (i.e. appendicitis or diverticulitis), trauma to the liver, or ablative therapies (TACE, RFA) used to treat liver cancer. Finally, distant infectious processes such as dental abscesses and endocarditis may cause liver abscess formation.
