Polycystic liver disease (PLD) is a rare genetic condition in which a person develops cysts throughout their liver.
Most people with PLD do not experience any symptoms. When symptoms do develop, they typically occur around the age of 50 years and may include abdominal pain, acid reflux, and shortness of breath. Doctors may treat the symptoms with medication and surgery.
This article describes what PLD is, including its symptoms, diagnosis, and treatment. It also outlines the life expectancy for people living with PLD.
PLD is a rare genetic condition characterized by the development of cysts within the liver. When a person has PLD, they have several mutations of the genes that build proteins in their liver’s epithelial cells. These mutations replace healthy liver tissue with fluid-filled cysts.
Usually, PLD runs in families, meaning that the mutations can persist across multiple generations. However, in
Liver cysts can also be an indication of the condition autosomal dominant polycystic kidney disease (ADPKD), in which cysts develop in the kidneys as well.
In fact, for many years,
Most people do not receive a diagnosis of PLD until they are about 50 years of age. Up to
To confirm the presence of liver cysts, doctors use imaging tests, such as:
However, before reaching a diagnosis of isolated PLD, a doctor
After looking at the scans, a doctor will apply Reynold’s criteria, which consider any risk factors that a person may have for PLD, including:
- family history
- any presenting symptoms of liver disease
Most people with PLD do not present with any symptoms. In such cases, treatment is not necessary.
People experiencing severe symptoms may require treatment to reduce cyst volume and liver size. Below, we outline some of these
Most drugs that doctors use to treat PLD are still in clinical trials, so it is difficult to draw conclusions about their long-term effectiveness and tolerability.
Octreotide is one drug that appears highly effective at reducing liver size. However, because this drug is expensive, doctors only recommend it when PLD severely affects a person’s quality of life.
Although researchers have not conducted any formal studies on estrogen receptor antagonists, which bind to receptors for the hormone estrogen, they may be of use. As estrogen plays a
Surgical techniques that a person with PLD may undergo include:
- Aspiration: A surgeon inserts a tube into the cysts to drain them. Depending on the extent of the procedure, a person will receive either a local or general anesthetic.
- Sclerotherapy: After a surgeon has drained the cysts, they may apply a chemical, such as ethanol, to destroy the cells that line the cysts. This helps prevent the cysts from refilling with fluid.
- Artery embolization: A surgeon places a thin tube in the blood vessel that supplies the cyst with blood. This blocks the vessel and starves the cyst of the nutrients and growth factors that it requires for growth.
- Laparoscopy: This is a type of keyhole surgery, during which the surgeon cuts open the cyst and removes the fluid and cells that line it.
- Partial liver resection: If there are many cysts growing on a particular area of the liver, a surgeon may recommend removing that part of the liver.
If a person does not respond well to medication or surgery, their doctor
No specific diet can prevent PLD. However, a well-balanced diet will help protect liver function.
Foods that a person should include in their diet:
- plenty of fruits and vegetables
- fiber-rich whole grains, for example, whole grain breads, rice, and cereals
- low fat dairy products
- lean cuts of meat and other sources of protein
Foods that a person should avoid include:
- processed foods that contain elevated levels of sugar, fat, and salt
- raw or uncooked shellfish, such as oysters and clams
To achieve the best possible health outcomes, people with PLD may require medical care from a range of healthcare professionals, including:
- primary care providers
Polycystic liver disease is a genetic condition that causes cysts to grow in the liver. Most people
Many of the drugs that could have a meaningful effect on PLD symptoms are still in clinical trials. However, people with severe symptoms may benefit from surgery to drain, destroy, or remove cysts. In very rare cases, a person may require a liver transplant to stop severe symptoms that have not responded well to medication or surgery.
Overall, people with PLD can expect to live a full life. Although it is not possible to prevent or cure PLD with diet, a well-balanced, low fat, fiber-rich diet can help protect liver function.
