Reviewer’ s report
Title: A rare hepatic mass in an Italian resident
Version: 0Date: 06 May 2020
Reviewer's report:1. I have attached the file which shows the edited Abstract I have done for you. I have included
track changes there so you could followup with similar changes in your manuscript. It is essential
that grammar and format is ideal prior to publication.
2. Your abscess is single with some outpouching and this should not be classified as 'multiple'
abscesses. It is wrong. The image doesn't show multiple. It is a single abscess with loculation. Sochange it please. Make this as single abscess. Also amend the following statement - "The threemajor nodules were 7 cm, 9 cm and 4 cm in diameter respectively (Fig 1, Panel A). ". Your casehas SINGLE ABSCESS. Report 1 size. You could report in 3 dimensions.
3. Mention full form of HIV . Authors need to consider full forms for all short forms4. Agree that large abscess should be drained. Antibiotics are NOT indicated on its own.
Percutaneous drainage + Antibiotics should be used togather. It appears you decided to managewith antibiotics along until patient deteriorated and than you decided to drain the abscess. This isnot ideal management as such. You are fortunate to save life by draining. It is advised thatdrainage should be done early for any patients with abscess > 4 cm size and this is shown indiverticular disease abscess as well as pyogenic liver abscess (PMID - 26133908). It is alsoimportant to note that you have rightly pointed out that rupture is a potentially dangerous
complication and this may warrant surgery. It is also important to note that rupture is less common
and majority of patients with giant abscess can be managed with drainage alone (PMID -26033361).
5. You started patient on meropenem and vancomycin. Is this based on local antibiogram? Is there
antibiotic stewardship program in your hospital? Please consider adding some discussion alongthese lines (PMID - 28785302)
