Reviewer's report:
Dear Authors,
Congratulations for your manuscript on such a rare and interesting case.
Nevertheless, I would like you to clarify some questions:
- what do you mean with "the porperties" in this sentence: "properties of brain
metastasis of PDAC are still unknown"?
- what was the "screening purpose" of the intial MDCT?
- why did you perform a brain MRI in the initial staging?
Best regards
