A section of a hydatid cyst

The cyst consists of a thick outer layer (*), several thinner internal layers, and many protoscolices.  The protoscolices are often called "hydatid sand."

Note the "hooks" that will form the hooks associated with the adult worm's armed rostellum.

Egg

An egg of Echinococcus granulosus(upper).

These eggs are virtually indistinguishable from other closely related species of tapeworms such as Taenia.

objects) Although these

tapeworms are quite small, a single dog can be infected with many of them.

Allergic reactions and sometimes anaphylactic shock

may occur if the cyst ruptures.

Ruptures of the cyst may also lead to the escape of protoscolices into the surrounding tissues, these can then develop into further cysts.

Diagnosis

Microscopy

Fluid aspirated from a hydatid cyst will shows multiple protoscolices (size approximately 100 µm), each of which has typical hooklets. 

The protoscolices are normally invaginated (left), and evaginated (middle, then right) when put in saline.

Antibody Detection

Indirect hemagglutination (IHA)

indirect fluorescent antibody (IFA) tests,

and enzyme immunoassays (EIA)

are sensitive tests for detecting antibodies

in serum of patients.

Treatment

Surgery is the most common form of treatment for echinococcosis .

The drug of choice

for treatment is albendazole .
