Hydatid cysts

Also called – echinococcosis, hydatidosis or hydatid disease

A hydatid cyst is like a little water balloon in your liver. It contains clear liquid and the young form of a parasite called a dog tape worm or echinococcus.

They are very rare in the UK. Most people with hydatid cysts will have got the condition overseas. It is more common in parts of Argentina, Peru, East Africa, Central Asia and China.

Treatment for hydatid cysts can involve draining them, taking medicines, or “watch and wait”.

Often the cysts do not cause any issues. But in very rare cases they can burst and cause a severe allergic reaction. This needs immediate medical help.
