Reviewer's report:  
 
The authors made significant correction to  the initial queries. The English written of the 
manuscript has improved. Here are my comments;  
 
-I think authors of this manuscript should write this abbreviation " 18F -FDG PET/CT" in full 
(fluorodeoxyglucose) in the title section.  
 
- The authors need to write more about Gastric Schwannoma and Fluorodeoxyglucose (18F) in 
the introductory section. Also, there are many researches or case report articles on the Gastric 
Schwannoma, I will urge the authors of this manuscript to compare the ir finding to other 
published articles on Gastric Schwannoma and the significant of Fluorodeoxyglucose (18F), and 
their main take home finding that make this manuscript different from previously published 
articles on Gastric Schwannoma. Very important.  
 
-The authors should create a limitation section and explain the limitation of their case study.
