Hepatic Calcification: Causes, Concerns, and Follow-Up

Calcification in the right liver lobe?

Hello Dr.
Chen, I underwent a health check at the joint outpatient center of the National Health Insurance Administration.
An abdominal ultrasound revealed a 0.55 cm calcification in the right liver lobe.
My AST is 23, ALT is 20, and other liver and biliary function test results are within normal ranges.
Could you please explain why there is calcification in my liver? Is it possible that it could be a tumor or other lesions? What precautions should I take, and how should I follow up? Thank you for your response.

Dr. Chen Jingwen reply Internal Medicine

Hello! Right hepatic calcification is generally caused by obstruction of the intrahepatic bile ducts or localized inflammation leading to fibrosis, which gradually calcifies.
It may also be due to a previous parasitic infection, where the source of infection (the parasite) dies and subsequently calcifies.
Additionally, it could be a trace of small vessel sclerosis (though your age does not suggest this as a likely cause).
Follow-up should be done every six months to a year.
Thank you for your question!

More Info

Hepatic calcification is a condition where calcium deposits form in the liver tissue. This phenomenon can be detected through imaging studies, such as an abdominal ultrasound, as you have experienced. The presence of calcification in the liver can arise from various causes, and understanding these causes is crucial for determining the appropriate follow-up and management.

Causes of Hepatic Calcification
1. Previous Infections: One of the most common causes of hepatic calcification is a history of infections, particularly parasitic infections like schistosomiasis or certain bacterial infections. These infections can lead to inflammation and subsequent calcification as the body attempts to heal.

2. Chronic Liver Disease: Conditions such as chronic hepatitis, cirrhosis, or fatty liver disease can also lead to calcification. Inflammation and necrosis of liver cells can result in mineral deposits.

3. Tumors: While benign tumors like hemangiomas can sometimes calcify, malignant tumors (cancers) can also present with calcification. However, the presence of calcification alone does not confirm malignancy.

4. Metabolic Disorders: Conditions that affect calcium metabolism, such as hyperparathyroidism or certain genetic disorders, can lead to calcification in various organs, including the liver.

5. Trauma or Surgery: Previous trauma to the liver or surgical interventions can also result in calcification as part of the healing process.

Concerns Regarding Hepatic Calcification
Given that your liver function tests (GOT and GPT) are within normal ranges, this is a positive sign indicating that there is no current significant liver dysfunction. However, the presence of calcification warrants further investigation to rule out any underlying conditions, especially if there are any associated symptoms or risk factors.

Follow-Up and Monitoring
1. Imaging Studies: It may be beneficial to follow up with additional imaging studies, such as a CT scan or MRI, which can provide more detailed information about the nature of the calcification. These imaging modalities can help differentiate between benign and potentially malignant processes.

2. Blood Tests: Regular monitoring of liver function tests and other relevant blood markers (such as tumor markers if indicated) can help assess any changes in liver health over time.

3. Clinical Evaluation: If you have any symptoms such as abdominal pain, jaundice, or unexplained weight loss, it is essential to discuss these with your healthcare provider, as they may necessitate more urgent evaluation.

4. Consultation with a Specialist: Depending on the findings from imaging and blood tests, a referral to a hepatologist or gastroenterologist may be warranted for further evaluation and management.

Conclusion
In summary, hepatic calcification can arise from various causes, and while your current liver function tests are normal, it is essential to follow up with appropriate imaging and clinical evaluations to ensure that no underlying pathology is present. Keeping an open line of communication with your healthcare provider and adhering to recommended follow-up appointments will be crucial in managing your liver health effectively. If you have any further questions or concerns, do not hesitate to reach out to your healthcare provider for personalized advice.

Hello, doctor. I would like to ask if hepatic nodular hyperplasia and calcifications in the liver are the same thing? If the fetal protein level is elevated at 17 and there are calcifications in the liver without hepatitis B or C, could this potentially indicate liver cancer?

Dr. Chen Shidian reply Gastroenterology and Hepatology
Nodules and calcifications should be considered different/unrelated. Elevated fetal protein levels are assessed by a gastroenterologist who monitors changes in values and conducts follow-up with ultrasound, computed tomography, or magnetic resonance imaging.
