Liver Cysts Overview
What Are Liver Cysts?
Liver cysts are fluid-filled sacs that form in the liver. Most liver cysts are benign (non-cancerous) and don’t cause symptoms, but occasionally, they may grow large enough to cause discomfort. They are usually found during imaging tests, like an ultrasound or CT scan, performed for other reasons.
Types of Liver Cysts:
Simple Cysts: These are the most common type and are typically harmless.
Polycystic Liver Disease (PLD): This condition causes multiple cysts to form and may be linked with kidney cysts.
Hydatid Cysts: Caused by a parasitic infection (Echinococcus), these cysts require treatment to prevent complications.
Biliary Cysts: These can block bile flow and may need surgical removal
Symptoms of Liver Cysts:
Most liver cysts do not cause symptoms. However, if a cyst becomes large, you may experience:
A feeling of fullness or discomfort in the upper right abdomen
Pain in the upper right side of the abdomen
Bloating or nausea
Diagnosis of Liver Cysts:
Liver cysts are often discovered incidentally during imaging tests. If a cyst appears suspicious, your doctor may recommend additional imaging or blood tests to determine if treatment is necessary.
Treatment of Liver Cysts:
When Is Treatment Needed?
Most liver cysts do not require treatment unless they are causing symptoms. If a cyst grows large or becomes painful, your doctor may suggest draining it or removing it surgically.
Surgical Options:
Laparoscopic Cyst Removal: This is a minimally invasive procedure where the surgeon makes small incisions to remove the cysts using special tools. It’s often done if the cyst is causing pain or is large
Drainage: Sometimes, if the cyst is filled with fluid, it can be drained using a needle and ultrasound guidance. However, this is often a temporary solution as cysts may refill
Long-Term Outlook:
For most people, liver cysts do not cause long-term problems. Once removed, simple cysts typically do not come back, and patients can return to normal activities soon after surgery.
