Uncommon locations of hydatid disease: A series of seven cases

Abstract

Echinococcosis is an infection caused in humans by larval stage of Echinococcus, especially Echinococcus granulosus and is endemic in the Middle East and Central Asia. Humans who act as intermediate host get infected incidentally by ingestion of eggs from the fecal matter. The eggs hatch inside the intestine, penetrate the walls enter portal circulation and lymphatic system eventually reaching the liver and lungs commonly. They can lodge in almost any part of body including brain, heart, and bones. There are two types of Echinococcus infections, Echinococcus granulosis and Echinococcus multilocularis. In this article, we are going to report atypical locations of hydatid disease with reference to review of literature.
