Echinococcosis is a parasitic disease caused by infection with tiny tapeworms of the genus Echinocococcus. Echinococcosis is classified as either cystic echinococcosis or alveolar echinococcosis. Liver cysts eventually cause abdominal pain or a palpable mass. Jaundice may occur if the bile duct is obstructed.
Pulmonary cysts can rupture, causing cough, chest pain, and hemoptysis. Surgery, sometimes via laparoscopy, can be curative. Albendazole is often given before surgery to prevent metastatic infections that can occur if cyst contents spill during the procedure.
