Title: Dynamic contrast -enhanced MR and PET/CT findings of uterine sarcomatoid 
carcinoma: a  case report  
 
Version: 0 Date: 09 May 2020  
 
Reviewer's report:  
 
A significant linguistic revision is needed.  
 
TITLE  
Since PET/CT was also acquired, I would suggest to include it in the title (e.g. MRI and 
PET/CT findings of sarcomatous carcinoma: a case report).  
 
ABSTRACT  
- it is stated in this section that MRI features of uterine sarcomatoid have not been reported. 
However, other cases have been published (e.g. 10.4103/0976 -7800.1277929).  
- case presentation, page 1, lines 17 -19: MRI features of a tumor are described but t he tumor 
was never mentioned before.  
 
CASE  
BACKGROUND  
- page 2, line 40, the sentence starting with "However" is not related to the previous 
paragraph.  
- PET/CT findings are reported but PET/CT was never mentioned before.  
- page 5, lines 95 -97, the sentenc e regarding US seems out of context.  
- more details on PET/CT can be added in the discussion section, e.g. comparison with other 
cases/studies.  
 
IMAGES  
- images should be zoomed on the pelvis.  
- Axial images should also be provided.
