Primary hydatid cyst of the maxillary sinus: case report

Hydatid disease (also known as hydatidosis) is a cyclozoonotic infection caused by the cestode genus Echinococcus. It occurs throughout the world and is especially common in sheep- and cattle-raising regions of Africa, Australia, New Zealand, India, the Middle East, South America, and the Mediterranean. The incidence of humans infected with hydatid disease is approximately 1.0-2.0:1,000, although it may be higher in rural areas of regions that are affected. Infection occurs via ingestion of infected meat. Primary infection of the maxillary antrum is odd and very rare. This article reviews a case report involving this rare condition.
