Abstract:

Hydatid cyst continues to be a health hazard in animal-raising countries. We encountered three male patients (ages 19, 30, and 50 years) with hydatid cysts exhibiting clinical and radiologic manifestations of malignancy. The lesions were localized on the right (n=2) and left (n=1). The patients complained of Claude-Bernard Horner syndrome, abundant hemoptysis accompanied by severe chest pain in the left hemithorax, and hemoptoic sputum and weight loss, respectively. Routine laboratory examinations and radiologic, ultrasonographic, bronchoscopic, and serologic investigations were performed in all patients. It was concluded that surgical interventions bay be required in order to make a definite diagnosis when findings from clinical, radiologic, bacteriologic, and bronchoscopic examinations are not adequate.
