First of all, let me tell you what exactly is a liver cyst? What causes this?

First of all, I want to make it clear to everyone that liver cyst is a benign lesion, and it is the most common benign lesion in the liver. The incidence rate is very high. Under normal circumstances, it will not become malignant and is basically the same as cancer. There is no connection.

In fact, a liver cyst is a blister that grows on our liver. It is very similar to the blister that grows on the body surface. I believe most people have had or seen a blister. It has a very thin wall. , the main content contained in it is water, and liver cysts are actually similar. Clinically, most liver cysts are simple liver cysts, which tend to be very smooth in appearance, generally round or oval in shape, and are mainly filled with liquid.

The specific pathogenesis of liver cyst is not particularly clear so far. Its wall is often somewhat similar to the epithelial tissue of the bile duct structure, but the liquid inside does not contain bile and is not connected to the bile duct system. . To sum up, liver cysts are benign lesions, similar to blisters, and have nothing to do with cancer. So do liver cysts have symptoms? How to diagnose?

Many people are confused as to why they usually feel fine and don’t have any discomfort, but then they find liver cysts during physical examination. In fact, this is a very normal phenomenon, because most liver cysts do not have any clinical symptoms.

In other words, you can't feel its existence at all. Unless the cyst has grown to a large size and compressed the adjacent liver tissue or other organs, some symptoms may appear, such as upper abdominal discomfort, dull pain in the right upper quadrant, a feeling of fullness quickly when eating, and feeling the upper right quadrant by touching it. Abdominal mass etc. In general, if these symptoms occur, it indicates that the cyst is relatively large and may need to be treated in time.

So how to diagnose liver cysts? In fact, the diagnosis of liver cysts mainly relies on imaging examinations, and the first choice is ultrasound examination. Many of our physical examination patients develop liver cysts, which are often discovered through ultrasound. On ultrasound, liver cysts appear as one or more cysts in the liver parenchyma. Multiple round or nearly round anechoic areas with thin walls and smooth edges, and no blood flow signal can be detected inside the lesions; in addition to ultrasonic examination, CT examination and MRI examination can also detect the presence of liver cysts, and Diagnosis of some complex liver cysts can also be made.

On CT, simple liver cysts generally appear as round low-density shadows with clear borders and generally uniform internal density. The CT value is approximately 0-20HU. If an enhanced scan is performed, the lesions will not show any enhancement. What should you do if you find a liver cyst?

I think this is also an issue that friends with liver cysts are most concerned about. First of all, for most simple liver cysts that do not cause any symptoms or signs, we do not need special treatment, we only need follow-up observation. It is usually recommended to perform a regular liver ultrasound examination every year to observe the changes in the cyst to see if it has enlarged and whether the components inside the lesion have changed.

Different patients often use different treatment methods. For specific treatment methods, you still need to consult a specialist at a local hospital to choose the best treatment method. Summary

Don’t worry too much about liver cysts. Although its pathogenesis is not obvious yet, we can clearly understand that it is a benign lesion and generally rarely undergoes malignant transformation. Therefore, if it is A liver cyst was found during a physical examination, but you don’t have any symptoms. You can rest assured that it will not have a bad impact on your body. You just need to have regular physical examinations.
