What is inside a hydatid cyst?
The larval form of the tapeworm may lodge in various body sites where they form a fluid-filled sac known as a hydatid cyst. The cysts contain immature forms of the tapeworm and can increase in size from 5–10 cm or more over a period of time. While some cysts may die, others can remain alive for many years.
What are the types of hydatid cyst?
Based on morphology the cyst can be classified into four different types 2:
- type I: simple cyst with no internal architecture.
- type II: cyst with daughter cyst(s) and matrix. type IIa: round daughter cysts at the periphery.
- type III: calcified cyst (dead cyst)
- type IV: complicated cyst, e.g. ruptured cyst.

What does hydatid disease mean?
Medical Definition of hydatid disease : a form of echinococcosis caused by the development of hydatids of a tapeworm of the genus Echinococcus (E. granulosus) in the tissues especially of the liver or lungs of humans and some domestic animals (as sheep and dogs) Learn More about hydatid disease
What is echinococcosis or hydatid disease?
Echinococcosis is an infection caused by either the Echinococcus granulosus or Echinococcus multilocularis tapeworm. The infection is also called hydatid disease. Humans become infected when they swallow the tapeworm eggs in contaminated food. The eggs then form cysts inside the body. A cyst is a closed pocket or pouch.
