The  authors  have  described  a  case  of  multiloculated  biliary  cystadenoma,  which  preoperatively  
mimicked a hydatic cyst. 
Though, this entity is not new and the authors have acknowledged this is a table, I think that more  
systematic workup would have given a correct preoperative diagnosis.
The authors have mentioned presence of calcification in radiology images, which is not apparent in  
figure 1. Please include a representative picture and put an indicative arrow. 
Preoperative eosinophil count was normal and radiological features were not typical of a hydatid cyst.  
The author should mention pre-operative serum IgE level. Please mention that. Moreover serum CA 19  
9 level was also not mentioned in the manuscript.
