Dysphonia and cervicomediastinal mass, very unusual presentation of hydatid cyst.

Hydatid disease, still endemic in developing countries, involves the liver and the lungs of the vast majority of cases. We report a very rare presentation of hydatid disease in a 35 year-old man with a cervicomediastinal mass and vocal cord paralysis, suspected of thyroid tumor. Surgery was curative and dysphonia disappeared completely. (Tanaffos 2010; 9(2): 61-63)
