We thank the authors for the interest shown in our article and describing the mechanism of pearl formation in detail. The mechanism of hydatid cyst formation was not the focus of our image, but rather the appearance of the membrane during diagnostic flexible bronchoscopy. Indeed, the hydatid membrane did appear like a pearl on bronchoscopic examination and certainly it is not due to some “light effect.” While the authors describe the pearl formation to a process of mineralization controlled by shell matrix gene, there are also claims that the natural pearl formation in fact is a host reaction to a foreign protein or an antigen most commonly a parasite.
