Reviewer’s report
Title: Biliary mucinous cystic neoplasm mimicking a hydatid cyst: a case report and literature review
Version: 2 Date: 22 Nov 2018
Reviewer: Paulo Herman
Reviewer's report:
This is a nice case report regarding the misdiagnosis of hydatic cyst and biliary mucinous cystic  
neoplasia (biliary cystadenoma).
I have just a few points regarding the paper:
- Authors should use biliary mucinous cystic neoplasia instead of biliary cystadenoma.
- Cyst location (right lobe) and epidemiology favored the diagnosis of a hydatic cyst; Comments on  
the preferred location (left lobe) of  biliary mucinous cystic neoplasia are lacking.
- I do agree that both lesions should be resected independently of a differential diagnosis however,  
authors should point out the risks of complication regarding hydatic cyst and biliary mucinous  
cystic neoplasia.
- Why did you prefer a righ hepatectomy instead of a pericystectomy?
- Figures 2 and 3 are not necessary.
