Cerebral hydatid cyst is a rare disease that occurs in children with a history of contact with dogs. The definite hosts of echinococcus are various carnivores – man is an accidental host. It is most often manifested by intracranial hypertension, seizures and focal neurological deficit.
What causes a hydatid cyst?, Cystic echinocccosis (CE), also known as hydatid disease, is caused by infection with the larval stage of Echinococcus granulosus, a ~2–7 millimeter long tapeworm found in dogs (definitive host) and sheep, cattle, goats, and pigs (intermediate hosts).
Furthermore, What is the meaning of hydatid cyst?, 1 : the larval cyst of a tapeworm of the genus Echinococcus that usually occurs as a fluid-filled sac containing daughter cysts in which scolices develop but that occasionally forms a proliferating spongy mass which actively metastasizes in the host’s tissues. — called also hydatid cyst.
Finally, How do humans develop hydatid cysts?, A person who comes in contact with the faeces of an infected dog (that is, when eggs from the tapeworm are passed in the faeces) may develop hydatid disease. This is serious and potentially fatal. Infection with tapeworm eggs causes cysts to form in vital organs such as the liver and lungs.
Frequently Asked Question:
What is inside a hydatid cyst?
The cysts found in those with cystic echinococcosis are usually filled with a clear fluid called hydatid fluid, are spherical, and typically consist of one compartment and are usually only found in one area of the body.
What happens when a hydatid cyst ruptures?
Rupture may lead to development of extrahepatic cysts and may also cause symptoms of an allergic origin such as marked eosinophilia, urticaria or anaphylaxis. More commonly, rupture occurs into bile ducts resulting in biliary obstruction, cholangitis, or biliary colic [2].
What causes hydatid cysts?
Cystic echinocccosis (CE), also known as hydatid disease, is caused by infection with the larval stage of Echinococcus granulosus, a ~2–7 millimeter long tapeworm found in dogs (definitive host) and sheep, cattle, goats, and pigs (intermediate hosts).
How do humans get infected with Echinococcus granulosus?
Humans are infected through ingestion of parasite eggs in contaminated food, water or soil, or after direct contact with animal hosts. Echinococcosis is often expensive and complicated to treat and may require extensive surgery and/or prolonged drug therapy.
What are the three types of hydatid formation?
Parasite morphology: Tape-worms form three different developmental stages: eggs; larvae; and adults.
Where do hydatid cysts form in humans?
Hydatid cysts are most commonly found in the liver and lungs, although they may also occur in other organs, bones and muscles. The cysts can increase in size to 5 – 10 cm or more and may survive for decades.

How is hydatid cyst diagnosed?
The diagnosis is most easily set by ultrasound or other imaging techniques such as CT-scan or MRI, combined with case history. Serology tests such as ELISA or immunoblotting can be used in addition, being 80-100% sensitive for liver cysts but only 50-56% for lungs and other organs [21].

How can hydatid disease be prevented?
Restrict home slaughter of sheep and other livestock. Do not consume any food or water that may have been contaminated by fecal matter from dogs. Wash your hands with soap and warm water after handling dogs, and before handling food. Teach children the importance of washing hands to prevent infection.
Who hydatid cyst treatment?
Two benzimidazolic drugs, mebendazole and albendazole, are the only anthelmintics effective against cystic echinococcosis. Albendazole and mebendazole are well tolerated but show different efficacy. Albendazole is significantly more effective than mebendazole in the treatment of liver cysts.
