Reviewer’s report
Title: 
Simultaneous brain and lung metastases of pancreatic ductal
adenocarcinoma after curative pancreatectomy: A case report and literature
review
Version:

Reviewer's report:
Are MRI brain and PET scan routinely done in all patients?
I suggest the word relapse does not suit in this sentence "and the
patient presented to our hospital with right-sided weakness and dysarthria. MRI
and CT showed
relapse of PDAC in the brain and lung, simultaneously." Please change it to
some appropriate word.
