Clinical InformationClinical

  • Echinococcosis

    an infection caused by the infestation of the larval form of tapeworms of the genus echinococcus. the liver, lungs, and kidney are the most common areas of infestation.

  • Echinococcosis, Hepatic

    liver disease caused by infections with parasitic tapeworms of the genus echinococcus, such as echinococcus granulosus or echinococcus multilocularis. ingested echinococcus ova burrow into the intestinal mucosa. the larval migration to the liver via the portal vein leads to watery vesicles (hydatid cyst).

  • Echinococcosis, Pulmonary

    helminth infection of the lung caused by echinococcus granulosus or echinococcus multilocularis.

  • Echinococcosis

    a parasitic infection caused by tapeworm larvae of echinococcus. it affects livestock and humans. it is characterized by the formation of hydatid cysts mainly in the liver, lungs, spleen, and kidneys. rupture of the cysts may lead to shock.

Patient EducationClinical

Parasitic Diseases

Parasites are living things that use other living things - like your body - for food and a place to live. You can get them from contaminated food or water, a bug bite, or sexual contact. Some parasitic diseases are easily treated and some are not.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
