Sir,
We would like to thank the author for the review and showing great interest in our
article. We would also like to thank them for the observations that they have made
as well as for clarifications.
Few cases of schwannoma were encountered by us. These had cystic/necrotic changes.
MR spectroscopy revealed lipid/lactate peak elevation with significant decrease in
choline integral values. However, more cases need to be evaluated related to the significance
of these findings.
We concur with the views expressed regarding previous few studies, where the results
have been expressed in terms of metabolite ratios.[1] However, pertaining to our study, where most of the lesions were diffused and histopathological
confirmation was available for cases, the comparison was made in relation to integral
values of the metabolites and deviation from normal spectra, and metabolite ratios
were not used.
