Round 1

Reviewer 1 Report

This case approach an interesting and practical issue in the diagnostic follow-up of disease by FDG-PET/CT. Metastases and radiation-induced liver disease may manifest as increased foci of FDG avidity at PET scanning. To be sure, an histological confirmation is the best way to obtain a differential diagnosis, but the evolution and appearance of the cases of radiation hepatitis and metastatic disease seem sufficiently distinctive.

 

The close comparison of PET ann MRI evolutive finding may be interesting to take into account this challenge situation as the authors had ilustrated in this case.

 

A couple of questions for the authors: can be use the ‘pseudoprogression’ concept in the discussion setting? Doeas the authors think a hepatitis may be the potential cause of their finding?

Reviewer 2 Report

The case presented can be considered for publication. However, the discussion of the case is not very thorough and would benefit from a better framing of the case in terms of clinical presentation and above all a discussion that would take into consideration the current state of the post-therapy follow-up procedures and the possible implications suggested by the case presented.
