Polycystic liver disease (PLD or PCLD) is a rare condition that causes cysts -- fluid-filled sacs -- to grow throughout the liver. A normal liver has a smooth, uniform appearance. A polycystic liver can look like a cluster of very large grapes. Cysts also can grow independently in different parts of the liver. The cysts, if they get too numerous or large, may cause discomfort and health complications. But most people with polycystic liver disease do not have symptoms and live a normal life.
Here are the facts about polycystic liver disease you need to better understand the condition.
The pancreas -- a spongy, tadpole-shaped organ located behind the stomach -- makes enzymes our bodies need to digest food and hormones to regulate blood sugar levels. If the pancreas is injured, its ducts, which carry enzyme-containing juices, can become blocked. This can lead to the development of a fluid-filled sac called a pancreatic pseudocyst.
A pseudocyst isn't a true cyst, because the wall of the sac is not composed of a specific lining of cells characteristic of a true cyst.
The most common...
The majority of people with polycystic liver disease inherit the condition, but PLD can occur randomly with no genetic link. Women are affected more often than men and tend to have more cysts.
PLD is most common in people who have polycystic kidney disease (PCKD), with its frequency increasing with age and advanced renal disease.
Most people don't discover they have PLD until they are adults, when the cysts become large enough to detect. Cysts can vary in size from no bigger than a pinhead to almost 4 inches wide. Likewise, your liver can stay its normal size or become extremely enlarged. No matter the number or size of cysts, polycystic livers continue to function normally and the disease is not considered life threatening.
Because it's inherited, if you or someone in your immediate family has PLD, other family members should be tested for it. Doctors can diagnose polycystic liver disease with imaging studies, such as ultrasound, CT scan, or MRI.
What Are the Symptoms of Polycystic Liver Disease?
Most of the time, people with polycystic liver disease have no symptoms. However, if the liver becomes enlarged and riddled with cysts, symptoms may include:
