Non-parasitic liver cysts

Laparoscopic Treatment Of A Giant Nonparasitic Cyst In Cirrhotic Liver (Health And Medical Video June 2018).

How is the non-parasitic liver cyst formed, how to diagnose the disease and what types of treatment exist.

Liver cysts, which are cavities with a liquid content, are limited by a wall, occur very often. In most cases, they are not recognized during life (only 1-2% of cases).

Types of non-parasitic liver cysts

Non-parasitic cysts are of two main types. Congenital (true) cysts are formed in a person in utero and in most cases, internally, are lined with a cubic or cylindrical epithelium.

The most common types of these liver cysts are most common:

  • Solitary cysts - isolated cysts (less often several), localized in different parts of the liver.
  • Polycystic ovary liver - a lot of cysts of different sizes, most often rounded forms, located adjacent to both parts of the liver (as opposed to solitary cysts). Polycystic ovary liver is often hereditary and in many cases combined with polycystosis of the kidneys, thyroid gland, lungs, mammary glands, pancreas and other organs.
  • Dermodies are congenital cysts, often containing heterogeneous tissue elements and inclusion.
  • The retinal cysts are formed in violation of the patency of various ducts and the accumulation of their secretions in the cyst cyst.
  • Cystadenomas - cysts formed from glandular tissue.

Acquired (false) cysts of the liver are formed during a person's life, often after a trauma to the abdominal organs (including sports, motor-road, etc.). In place of hematoma. Inside, they, unlike true cysts, are covered not with an epithelium, but with a layer of connective tissue. Depending on the number of them, they are subdivided into solitary and plural ones.

Any cyst may be a single round cavity containing only liquid or liquid, including colloidal, content with the inclusion of more dense fragments.

There are cysts with partitions, dense and barely noticeable walls, areas of grafting both in the bone itself and in its wall.

Clinical manifestations

Often, small non-parasitic cysts are an accidental discovery in studies conducted on other occasions.

However, with a large amount of cysts can give non-typical symptoms in the form of small or moderately pronounced permanent dull pains in the right hypochondrium, and sometimes even determined by palpation (tufts), especially in the left fossa of the liver, almost uncovered by the edge arc. In some cases, complications may develop.

The most frequent


Such complications include the following diseases and conditions:

  • Rupture of the cyst;
  • Cystic suppuration;
  • Hemorrhage into the cyst;
  • Malignant degeneration (malignancy);
  • Tipping the cyst on the leg (often accompanied by a clinical picture of the acute abdomen);
  • Jaundice, which is obturational by compression of the cyst of large bile ducts;
  • Development of symptoms of hepatic failure (more common in polycystic ovaries, when a significant part of the liver tissue is replaced by cysts);
  • Development of symptoms of renal failure (often accompanied by hepatic insufficiency with polycysteine, the prognosis of the disease in this case is unfavorable).


There are the following types of diagnostics:

  • Ultrasound (can diagnose liver cysts with a diameter of more than 5 mm in almost 100% of cases);
  • Computed tomography with angiography;
  • Magnetic resonance imaging (sometimes with angiography);
  • Biochemical analyzes (often help only with the development of complications);
  • Immunological (serological) studies that help distinguish nonparasittic cysts from parasitic;
  • Puncture biopsy under the control of ultrasound (also used for refinement and differential diagnosis);
  • Endoscopic laparoscopy (performed for differential diagnosis, and in some cases for therapeutic purposes).


Treatment depends on the course of the disease and individual characteristics. At small cysts, which do not violate the permeability of the duct, there is no need for surgical treatment.

The main method of treating medium-sized solitary cysts is a puncture under the control of an ultrasound or CT with removal of the contents and introduction into the sclerosing drug (most often it is a mixture of 96 percent ethyl alcohol with 87 percent glycerol). As a result, the internal wall of the cyst is necrotized, cyst gradually falling and scratched. This procedure is very effective and often does not complicate.

Treatment of polycystosis in the liver operatively is rarely carried out and is excision of the walls of cysts using a laser or electro nose with subsequent sclerotherapy.
