Reviewer’s report
Title: 
Pneumatosis cystoides intestinalis associated with etoposide in
hematological malignancies: A case report and a literature review
Version: 
1 
Date: 
15 Feb 2022
Reviewer's report:
I would like to thank the authors for re-submission of their work. 
1. English errors continue to persist, although there have been improvements.
For instance, in line 65 "on entry" is not incorrect, but is an unusual phrase and
sounds out of place. Similarly in line 26 the phrase "and lack specific symptoms,
leaving no accurate morbidity" would benefit from re-wording. 
2. The authors make a point to say that imaging is how PI has been increasingly
diagnosed, yet the exploratory laparotomy in this case made the diagnosis while
the CT findings were equivocal. This should be emphasized in the discussion
section. 
3. If possible, the CT images would benefit from being in the same view (the pre
images are in a Lung view setting while the post images are in an Abdomen
view)
