PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: The case report is novel. The case is well described
with clinical information and relevant imaging provided. The description and
interpretation is appropriate. The accompanying discussion could be
strengthened to further draw out key learning points for the reader. The
manuscript requires some further review for the correct use of medical English.
REQUESTED REVISIONS: 
Thank you for the opportunity to review this novel case report. I have some
comments and questions for the authors:
1) The introduction is brief and could be broadened to help set the context of
MANEC and the contribution this case report makes. e.g. the first sentence of
the second para in the discussion would be better placed in the introduction to
provide that useful background at the start. 
2) The discussion contains some repetition, e.g. the first line of the first para
repeats similar background already provided in the introduction
3) The inclusion of previous findings from a literature review in the discussion is
helpful. Could the key points be better outlined in a table?
4) The conclusion could help concisely convey the key learning points from this
case more clearly
5) The manuscript would benefit from a review of the medical English grammar
throughout.
