Reviewer's report:  
 
This case -report is well -written, concise and straight to the point.  
 
 
It is w orthy of interest to publish as it is an unfrequent pathology.  
 
 
The summary of the previous cases in the literature in table 1 is interesting as it gives a rapid 
overview of this situation.  
 
 
Minor suggestions:  
 
- could the authors detail the risk factors associated with CC?  
 
- it would be interesting if the authors could discuss potential risk factors for perforation in
