Pulmonary hydatid cyst in Thai: A report of first case.

ABSTRACT

The first case of Pulmonary Hydatid Cyst at the Central Chest Hospital was recently found in a Thai male presenting with haemoptysis. His chest x-ray revealed a round mass (2.5x3.5 cm) with distinct border at the anterior segment of the left upper lobe. The diagnosis of lung cyst was made by ultrasonography. Examination of aspirated cyst fluid revealed Echinococcus granulosus parasite. Left thoracotomy was performed to remove the cyst; there was no post-operative complication.
