What is hydatid cyst

Echinococcosis is a parasitic disease caused by infection with tiny tapeworms of the genus Echinocococcus.

Hydatid disease is caused by infection with a small tapeworm parasite called Echinococcus granulosus. In Australia, most infections are passed between sheep and dogs, although other animals including goats, horses, kangaroos, dingoes and foxes may be involved. The hydatid parasite is carried by dogs in their bowel, without any symptoms of infection. Sheep become infected while grazing in areas contaminated with dog faeces. Dogs become infected by eating the uncooked organs of infected sheep. People become infected by ingesting eating eggs of the parasite, usually when there is hand-to-mouth transfer of eggs in dog faeces. This can occur when handling dogs or objects including food and water soiled with dog faeces.

Hydatid disease HD is a unique parasitic disease that primarily affects the liver and is endemic in many parts of the world. There are four types of hydatid cysts HCs with various levels of organ involvement. All four HC types can be seen in the liver, with the right lobe being the most common site of involvement. There are many potential intrahepatic and extrahepatic complications that affect the liver and other organs. Intrahepatic complications include vascular and biliary complications and infection. With rare portal vein compression and decreased vascular supply, the involved lobe may show atrophic changes while the other lobe becomes hypertrophic. Intrahepatic biliary dilatation results from large cysts compressing intrahepatic ducts or due to cyst rupture into the biliary ducts. Cyst infection may also occur via a similar mechanism. Extrahepatic complications result from exophytic growth and hematogeneous dissemination. Exophytic growth causes migration of cysts into the lungs, mediastinum, heart and peritoneum. Hematogeneous dissemination involves all other organs.

The complications of hydatid disease in liver Mass effect One of the most important complications occurs when HCs type I and II reach large sizes due to an active growth phase. Your first tests will probably be a liver blood test and an ultrasound scan. All types of HCs can be seen within the liver, what is hydatid cyst.

Variable, from months to years, depending upon the number and location of cysts and how rapidly they grow. CT is superior in detecting gas or air-fluid levels within the cyst Figure The definitive host becomes infected by ingesting the cyst-containing organs of the infected intermediate host.

Rupture can also be seen in these locations due to a lack of protective tissue surrounding the cyst and deficient pericyct. Although Type I HCs cannot spread to host parenchyma other than by external rupture, type II HCs can be spread to nearby tissue by outpouching a new cyst from main cyst cavity. There are several different drugs used to treat hydatid cysts.

Most are harmless, but they should be removed when possible because they occasionally may change into malignant growths, become infected, or obstruct a gland. There are four main types of cysts: retention cysts , exudation cysts , embryonic cysts , and parasitic cysts. Baker cyst a swelling on the back of the knee, due to escape of synovial fluid that has become enclosed in a sac of membrane.

Cystic content is marked in newly ruptured HC. Exophytic growth The two most common routes of exophytic growth are via the bare area of the liver and gastrohepatic ligament. Blood tests to check the person's immune response to the parasite may be useful, but are not always positive even when an infection is present.
