It is not clear what you mean with diff value, is that field 6 or field 10. Also is the difference only >10 or also <-10 :
Here is an example you could try with $6 and both negative and positive, to give you an idea of how this might be approached:

Code:
$ awk '$1=="Comparing"{p=$0} $1=="Line" && ($6>10 || $6<-10) {if(p){print p; p=x} print}' infile

mincdiff

MINCDIFF(1)							 MINC User's Guide						       MINCDIFF(1)

NAME

       mincdiff - report differences between minc files

SYNOPSIS

       mincdiff [-header|-body] [-l] [diff options] file1 file2

DESCRIPTION

       The  mincdiff  shell  script compares two minc files by running diff(1) on the headers of the two minc files, and cmp(1) on the image vari-
       able.  You can view only the header differences using -header or only the body (image variable) differences using -body.  The option -l	is
       passed on to cmp of the image variable.	Any unrecognized options (e.g. -u) are passed verbatim to the diff of the headers.

OPTIONS

       -header Compare only the headers of the two files.

       -body Compare only the image data of the two files.

       -l Print the byte offset in decimal and the byte value in octal
	      for each difference encountered in the image variable.
