Lung Cyst Hydatid Extracted via Bronchoscopy and the Necessity of Surgery: A Case Report.

Abstract

Echinococcus granulosus remains a global public health issue. Although predominantly affecting the liver, the lungs are the second most affected organ and often undergo surgical intervention. Here, a case managed by bronchoscopy and medical therapy is presented. A 26-year-old woman was presented with a cough, hemoptysis, and a 5 kg weight loss in the last two months. Chest imaging identified a 4 cm centrally cystic mass lesion in the middle lobe of the right lung, which was suspicious of lung cancer. Bronchoscopy revealed a whitish, plastic-like object that was difficult to extricate and obstructed the middle lobe bronchus. We removed the material and purulent secretions covering it and opened the middle lobe bronchus totally. The histopathological study verified its consistency with hydatid cyst. There was no evidence of a hydatid cyst on computerized thomography after bronchoscopy. The lesion in the left lobe of the liver, confirmed to be suggestive of a hydatid cyst via ultrasonography, was treated using the PAIR technique. We administered oral albendazole to continue the treatment. It may be a reasonable approach to postpone surgery in order to preserve lung tissue in patients who have undergone complete removal of hydatid cyst material via bronchoscope.
