My DD's FSIQ was similar, and the profile was also similar, though the spread was a bit less extreme (verbal in the 120s, visual around 142). And in her case, that's an accurate profile, highlighting her strengths and weaknesses.

You can tell you have a visual-spatial processor in your house when, every time she tells an anecdote, she tries to reenact it with whatever objects are at hand (stuffed animals, salt/pepper shakers, etc.). She was doing this starting around 3.
