Polycystic Liver Disease: Symptoms, Causes and Treatment Options

Key Words: polycystic liver, polycystic liver disease, liver cyst, liver diseases, liver treatment, cystic diseases, liver cyst symptoms, is polycystic liver genetic?

The liver is the largest internal organ in our body and carries out vital functions. However, certain genetic and structural disorders can cause cystic formations in the liver. One such condition is known as polycystic liver disease . Although rare, early diagnosis and treatment can significantly improve quality of life.

In this article, we will cover many details such as what is polycystic liver disease, what are its symptoms, who is affected, and what are the diagnosis and treatment processes.

What is Polycystic Liver Disease?

Polycystic liver disease (PCLD) is a genetic disorder characterized by the formation of multiple cysts (fluid-filled sacs) in the liver. These cysts can grow and increase in number over time, complicating liver function.

This disease is often seen in conjunction with autosomal dominant polycystic kidney disease (ADPKD) . However, in some cases, cysts are found only in the liver; this is called isolated polycystic liver disease .

What are the reasons?

The most common cause of polycystic liver disease is genetic mutations . These genetic disorders prevent the normal development of the bile ducts in the liver, leading to cyst formation.

The main genetic causes are:

• PKD1 and PKD2 gene mutations (associated with ADPKD)

• PRKCSH and SEC63 gene mutations (associated with isolated liver cysts)

Additionally, some conditions can accelerate the growth of cysts:

• Estrogen hormone (more common in women)

• Pregnancy

• Long-term use of birth control pills

What are the symptoms?

Most individuals with polycystic liver disease do not experience any symptoms in the early stages of the disease. However, as cysts grow and increase liver volume, certain symptoms may appear:

• A feeling of fullness in the abdomen

• Pain in the upper right abdomen

• Swelling

• Shortness of breath (due to the liver pressing on the stomach and diaphragm)

• Loss of appetite and weight loss

• Indigestion

• Rarely, obstruction of the bile ducts

These symptoms may vary depending on the number and size of the cysts.

Who is at Risk?

• People with genetic predisposition

• Women (especially women who have given birth multiple times)

• ADPKD patients

• Those who have been on estrogen therapy for a long time

Diagnostic Methods

Diagnosis of polycystic liver disease is usually made through imaging studies. In some cases, cysts are discovered incidentally during scans.

Main diagnostic methods:

• Ultrasonography (USG): It is the most widely used and easily accessible method.

• Computed Tomography (CT): Provides detailed information about the number, size and spread of cysts.

• Magnetic Resonance Imaging (MRI): It is used especially for detailed examination of liver tissue.

• Genetic testing: Can be performed to clarify the diagnosis in individuals with a family history.

What is the difference between a liver cyst and polycystic liver?

Not every liver cyst indicates polycystic liver disease. Single or multiple small cysts are common and generally harmless. Polycystic liver disease can have dozens or even hundreds of cysts and can be progressive.

Treatment Options

Treatment of polycystic liver disease varies depending on the severity of the disease, the size of the cysts, and the patient's quality of life.

1. Monitoring and Observation

Mild cases do not require treatment. Asymptomatic patients are monitored regularly.

2. Medication

• Estrogen-reducing medications: It is thought that estrogen may increase cyst growth in female patients.

• mTOR inhibitors, such as sirolimus and everolimus: These investigational drugs may slow cyst growth.

3. Interventional Methods

• Cyst drainage and sclerotherapy: Large cysts are drained with a needle, and alcohol may be applied to prevent refilling.

• Cystectomy: Surgical removal of cysts. It is generally preferred in symptomatic cases.

• Liver resection: Surgical removal of the part of the liver where cysts are concentrated.

4. Liver Transplant

In rare but most advanced cases, liver transplantation may be the only option. It is considered for patients who develop organ failure or who have not responded to other treatments.

Lifestyle and Nutrition Tips

Although it is not possible to completely prevent polycystic liver disease, some lifestyle changes can positively affect the course of the disease:

• Balanced and healthy diet: Foods rich in fiber, low in fat and antioxidants should be preferred.

• Avoiding alcohol consumption

• Limiting salt and sugar intake

• Maintaining ideal weight

• Regular doctor check-ups

Frequently Asked Questions (FAQ) About Polycystic Liver Disease

Can polycystic liver disease be completely cured?

No, because it is a genetic disease, it cannot be cured completely. However, it can be managed with appropriate monitoring and treatment.

Do cysts become cancerous?

Liver cysts are generally benign and the risk of becoming cancerous is quite low.

Does it pose a risk during pregnancy?

Pregnancy hormones can increase cyst growth. Therefore, a doctor's checkup is recommended before pregnancy.

Polycystic liver disease is a rare but potentially serious liver disease. Early diagnosis, regular follow-up, and appropriate treatment can improve patients' quality of life.
