Abstract

Hydatid cyst disease, which is caused by Echinococcus granulosus and Echinococcus multilocularis, is a frequent zoonotic enfestation worldwide. The most often affected organs are liver (%65) and lungs (%25) in human beings. Thyroid gland involvement is very rare even in regions where the disease is endemic. In this study, two rare cases, at the ages of 70 and 15, who were admitted to the hospital with swelling in the neck and diagnosed as thyroid cyst hydatid was presented.
