A middle-aged gentleman, nonsmoker, presented with complaints of right-sided chest discomfort for 6 months. There was no fever, cough, expectoration, or hemoptysis. Chest radiograph suggested a mass lesion in the right upper zone. A contrast-enhanced computed tomography demonstrated a well-defined cystic lesion with small air foci at periphery of the lesion (air-bubble sign) and contrast enhancement of cyst wall (ring enhancement sign) [Figure 1]a. Flexible bronchoscopy showed a glistening pearly white membranous structure occluding the lumen of the right upper lobe anterior segment (RB3). For diagnosis, a cryoprobe was used [Video 1], which yielded a portion of the membrane. Histopathological examination revealed a degenerated hydatid cyst. The patient was initiated on albendazole therapy and is scheduled for surgical resection. Endobronchial visualization of hydatid membranes can be seen in about 20% of pulmonary hydatid cases., The imaging and bronchoscopic appearance in the index case is characteristic of an intact hydatid cyst [Figure 1]b. The mechanism of formation of hydatid cyst (hosts reaction to a parasite) is quite analogs to the formation of natural pearls, hence the title.
