Most liver cysts are detected during a physical examination with an ultrasound. Ultrasound is also the preferred, cost-effective, reliable and non-invasive simple method for periodic review of liver cysts. Symptom-wise: most of them have no uncomfortable symptoms. Medical history: Most have no history of hepatitis or cirrhosis. Laboratory tests: AFP negative, liver function mostly normal; liver cysts usually do not cause liver function abnormalities, and liver function laboratory tests are of little diagnostic value for smaller liver cysts; after liver cysts are found, blood should be taken for methemoglobin to help exclude primary liver cancer. In terms of imaging examination: B-type ultrasonography can detect almost all liver cysts, and the detection rate of liver cysts can reach 98%, while liver encapsulation disease can be identified. In terms of characterization, ultrasonography CT is more accurate; however, to fully understand the size, number and location of cysts, especially those huge liver cysts that need to be treated surgically, CT is better than ultrasonography. In short, don’t be nervous if you have liver cysts, they are common benign liver diseases, and they are not cancerous in general, most of them don’t damage liver function, and small cysts don’t affect normal life. Since there is no special medicine to eliminate liver cysts, there is no need to take medicine to treat them, so you only need to go to the hospital for regular review and 1-2 ultrasound times a year.
