Pulmonary hydatid cyst: Review of literature.

Echinococcosis is a rare infectious disease in human being that occurs by the larval stages of taeniid cestodes of the genus Echinococcus. Human cystic echinococcosis is the most common presentation. The liver is the most common site of echinococcal cyst, followed by the lungs. The symptoms of lung infestation lead to sudden onset of chest pain, cough, fever, and hemoptysis after a cyst rupture. The diagnosis is confirmed by radiology supplemented with serology. Chest X-ray and computer tomography of chest is the principal investigation for pulmonary hydatid cyst (PHC). The treatment of PHCs is either pharmacotherapy and/or surgery. Surgical intervention is the most preferred treatment of choice; pharmacotherapy is useful in selected patients. Pharmacotherapy includes oral administration of benzimidazoles group of drugs like mebendazole or albendazole.
