Pulmonary hydatid cyst--a case report.

Hydatid disease is caused by Echinococcus granulosus parasite. It affects most commonly the liver, followed by the lungs. Symptoms are not specific and can be produced by the mass effect or cyst complications. Early identification and treatment of the condition prevents mortality. We report a case of pulmonary hydatid cyst, where the patient presented with symptoms of fever, cough with expectoration, weight loss and dyspnoea. Final diagnosis was done based on chest radiography and Tomography scan findings and was successfully treated with right middle lobectomy and anti-helminthic drugs.
